All you need to know about "The Rohingya Migrant Crisis"

Introduction:
  • Tens of thousands of Muslim Rohingya have fled Myanmar in the past year, many of them taking to the sea in the spring of 2015 to try to reach Indonesia, Malaysia, and Thailand. 
  • The latest surge in refugees was prompted by a long-building crisis: the discriminatory policies of the Myanmar government in Rakhine State, which have caused hundreds of thousands of Rohingya to flee since the late 1970s.
  • Their plight has been compounded by the responses of many of Myanmar’s neighbors, which have been slow to take in the refugees for fear of a migrant influx they feel incapable of handling.

Who are the Rohingya?
  • The Rohingya are an ethnic Muslim minority group living primarily in Myanmar's western Rakhine State; they practice a Sufi-inflected variation of Sunni Islam. 
  • The estimated one million Rohingya in Myanmar account for nearly a third of Rakhine state's population. 
  • The Rohingya differ from Myanmar’s dominant Buddhist groups ethnically, linguistically, and religiously.
  • The Rohingya trace their origins in the region back to the fifteenth century when thousands of Muslims came to the former Arakan Kingdom. Many others arrived during the nineteenth and early twentieth centuries when Bengal and the Rakhine territory were governed by colonial rule as part of British India. 
  • Since independence in 1948, successive governments in Burma, renamed Myanmar in 1989, have refuted the Rohingya's historical claims and denied the group recognition as one of the country's 135 ethnic groups. 
  • The Rohingya are largely identified as illegal Bengali immigrants, despite the fact that many Rohingya have resided in Myanmar for centuries.
  • Both the Myanmar government and the Rakhine state’s dominant ethnic Buddhist group, known as the Rakhine, reject the use of the label "Rohingya," a self-identifying term that surfaced in the 1950s and that experts say provides the group with a collective, political identity. 
  • Though the etymological root of the word is disputed, the most widely accepted origin is that "Rohang" is a derivation of the word "Arakan" in the Rohingya dialect and the "ga" or "gya" means "from."
  • By identifying as Rohingya, the ethnic Muslim group asserts its ties to land that was once under the control of the Arakan Kingdom, according to Chris Lewa, director of the Arakan Project, a Thailand-based advocacy group.

What is the legal status of the Rohingya?
  • The Myanmar government refuses to grant the Rohingya citizenship status and, as a result, the vast majority of the group's members have no legal documentation, effectively making them stateless. 
  • Though Myanmar's 1948 citizenship law was already exclusionary, the military junta introduced a citizenship law in 1982 whose strict provisions stripped the Rohingya of access to full citizenship. 
  • Until recently, the Rohingya have been able to register as temporary residents with temporary identification cards, known as "white cards," which Myanmar's regime began issuing to many Muslims (both Rohingya and non-Rohingya) in the 1990s. 
  • The white cardsconferred  some limited rights but were not recognized as proof of citizenship. Although the temporary cards held no legal value, Lewa says that the IDs did represent some minimal recognition of temporary stay for the Rohingya in Myanmar.
  • In 2014 the government held a UN-backed national census—its first in thirty years. The Muslim minority group was initially permitted to self-identify as "Rohingya," but after Buddhist nationalists threatened to boycott the census, the government decided the Rohingya could only register if they identified themselves as Bengali.
  • Similarly, under pressure from Buddhist nationalists protesting Rohingyas’ right to vote in a 2015 constitutional referendum, President Thein Sein cancelled the temporary ID cards in February 2015, effectively revoking their newly gained right to vote—white card holders were allowed to vote in Myanmar's 2008 constitutional referendum and 2010 general elections. "Country-wide anti-Muslim sentiment makes it politically difficult for the [central] government to take steps seen as supportive of Muslim rights," writes the International Crisis Group.
  • Despite the documentation by rights groups of systematic disenfranchisement, violence, and instances of anti-Muslim campaigns, Muslim minorities continue to "consolidate under one Rohingya identity" says Lewa.
Where are they migrating?
  • Many Rohingya have sought refuge in nearby Bangladesh, which hosts more than thirty-two thousand registered refugees; more than two hundred additional unregistered Rohingya refugees are believed to live in the country, according to UN High Commissioner for Refugees (UNHCR) estimates. 
  • However, conditions in the most of the country’s refugee camps are dire, driving many to risk a perilous voyage in the Bay of Bengal.
What is the role of the Association of Southeast Asian Nations (ASEAN) and international actors in resolving the migration crisis?
  • No unified or coordinated ASEAN response has been proposed or developed to address the deepening crisis. States in Southeast Asia also lack established legal frameworks to provide for the protection of rights for refugees.
  • Indonesia, Malaysia, Myanmar, and Thailand—all ASEAN members—have yet to ratify the UN Refugee Convention and its Protocol. ASEAN itself has remained silent on the plight of the Rohingya and on the growing numbers of asylum-seekers in member countries largely because of the organization’s commitment to the fundamental principleof noninterference in the internal affairs of member-states. Lilianne Fan of the London-based Overseas Development Institute says that while ASEAN has the capacity to manage this crisis, member states lack the political will to resolve it.
  • Advocacy groups like Human Rights Watch, the Arakan Project, and Fortify Rights, a Southeast Asia-based advocacy group, continue to appeal to major international players to exert pressure on Myanmar's government. Some, like New York Times columnist Nicholas Kristof, argue that the United States should not have normal relations with the country until its persecution of the Rohingya ends. Others, like senior advisor at the United States Institute of Peace and former U.S. mission chief in Myanmar Priscilla Clapp, say that placing sole blame on Myanmar oversimplifies and misrepresents the complexities of the country's historical ethnic diversity. "An international response that consists primarily of assigning blame for this humanitarian tragedy is no longer tenable. It is time for the international community to organize a realistic, workable solution," writes Clapp.
  • To date, the United States and other global powers have urged the central government in Myanmar to do more to protect ethnic minority groups from persecution. On a visit to Myanmar in the fall 2014, U.S. President Barack Obama said, "Discrimination against a Rohingya or any other religious minority… does not express the kind of country that Burma over the long term wants to be."
  • Though no coherent regional or international response to the migrant crisis has come to fruition, more pointed international pressure appears to be mounting against Myanmar's central government. U.S. Assistant Secretary of State for Population, Refugees, and Migration Anne Richard said in May that resettlement fails to address the plight of the Rohingya in Myanmar. "The answer to the issue is peace and stability and citizenship for the Rohingyas in Rakhine State, and that is the solution."
Future: apprehensions and hope
  • The Rohingyas have also tried to overcome their hardships by establishing rudimentary schools; by helping one another find work; and by joining organizations that provide services, advice and a sense of solidarity. The United Nations High Commissioner for Refugees said it was supporting 31 “learning centers” across Malaysia for Rohingya children. Other schools operate without United Nations support. It is only seldom that the Rohingyas use their communal solidarity as a form of security for themselves.
  • Bangladesh has offered to relocate the 32,000 registered refugees to an inhabited island called Thengar Char, two hours away from the mainland. Not only is such a large scale move logistically impractical, but also the island disappears under floodwater for a few good months during the monsoon and is visited by pirates. Their ‘home country’ Myanmar has banned the community from fleeing, but refuses to address the problem. Pakistan’s permanent representative at the UN has suggested for the cause to be taken up to the UN Secretary General Ban ki Moon, and that the recent resolution adopted on Rohingya Muslims at a Ministerial meeting of the Organization of Islamic Cooperation (OIC) be sent to the President of the Security Council. Malaysia and Indonesia have agreed to provide temporary asylum to 7000 migrants. Fate of thousands of the beleaguered community remains dark as they flee from one country to another in search of a basic need: an identity.

[History] 200 Years of Gorkha Brigade/Anglo–Nepalese War

[Issue in News: 200 Years+Location:Nepal this year for Earthquake]
Date: 1814–1816
Location: Kingdom of Nepal
Between: Kingdom of Nepal & British East India Company

During The Governorshp in India: Lord Moira
During Prime Minister Nepal: Bhimsen Thapa
Result: East India Company victory [The war ended with the signing of the Treaty of Sugauli in 1816, which ceded around a third of Nepal's territory to the British.]
They are one of the most feared soldiers in the world and have won the respects of even their enemies. The Gorkhas were integrated with the Indian Forces on April 24, 1815. Over time they have served in all theatres of war and won many military decorations. Here are some facts about the most respected regiment of the Indian Army.

The Gorkha Rifles, who have made a name for themselves across the globe with their exemplary courage and bravery, have completed 200 years of soldiering.

Brief history:
  • It was raised in 1815.
  • During the early 18th century, the Gorkhas from Nepal had extended their empire into Kumaon, Garhwal and Kangra Hills. This led to a confrontation with the British East India Company, resulting in the Gorkha War of 1815.
  • Impressed by the fighting qualities of the Gorkhas, the East India Company offered to raise a Gorkha Regiment from the remnants of General Amar Singh Thapa’s army after the treaty of Sigauli.
  • Thus, the First Nusseree (meaning friendly or loyal) Battalion came into being on April 24, 1815 at Subathu in Shimla Hills, the present home of the 14 Gorkha Training Centre.
  • Since its raising, the Regiment has undergone a number of changes in its titles, the present being Third Gorkha Rifles.
  • The war cry of the Battalion is “Aayo Gorkhali”.
  • There are roughly around 30,000 Nepalese Gorkhas currently serving in the Indian Army’s seven Gorkha Rifles or regiments (Ist, 3rd, 4th, 5th, 8th, 9th, and 11th), each of which has five to six battalions (around 600 fighting soldiers each). The 200 years of service of the Gorkhas is also being marked by the British Army.
Facts About The Gorkha Regiment That Completes 200 Years In The Indian Army:
  1. So impressed were the British by the fighting skills and valour of the Gorkha soldiers in the Anglo Nepal War of 1814-16, that they were quick to integrate them in the British Indian Army.
  2. They weren’t raised as the Gorkha Regiment however. Instead it was called the Nasiri Regiment. The regiment was later renamed 1st King George’s Own Gurkha Rifles.
  3. After India’s Independence, six regiments, the 1 GR, 3 GR, 4 GR, 5 GR, 8 GR and 9 GR were retained in the Indian Army, while 2nd, 6th, 7th and 10th joined the Brigade of Gurkhas in the British Army.
  4. Another regiment was raised by the Indian Army, the 11 GR, to accommodate the soldiers who refused to be transferred to the British Army.
  5. The Gorkha units are some of the most decorated in the Army. They have played an important role in all the wars and have won Battle Honours in Uri sector in 1947-48, Ladakh in 1962, Jammu and Kashmir in 1965 and 1971. They were also a part of the Indian Peace Keeping Force in Sri Lanka.
  6. The Gorkha Regiments have been awarded 3 Param Vir Chakras, 33 Maha Vir Chakras, and 84 Vir Chakras during operations.
  7. The Regimental Insignia of all the Gorkha Rifles Regiments consists of a pair of crossed khukris. The khukri is a curved Nepalese knife which all Gorkha Rifles soldiers carry as a personal weapon.
  8. The Gorkha Regiment also has a tradition of sacrificing a male buffalo on the festival of Dusshera. The head of the buffalo has to be severed in one clean sweep of the khukri. Usually the youngest member of the unit gets the privilege.
  9. Field Marshal Manekshaw, who’s parent unit was 12th Frontier Force Regiment that moved to the Pakistani Army, became a part of the 8 GR. He would later become the Colonel of the regiment of the unit. He once famously said “If a man says he is not afraid of dying, he is either lying or is a Gorkha.”
  10. The war cry of the Gorkha Regiments is ‘Jai Maha Kali, Ayo Gorkhali’ which translates to Hail Goddess Kali, The Gorkhas Are Here.
  11. Officers in the Gorkha Regiments of the Indian Army have to learn the Gorkhali language to be able to interact with their men in their native tongue.
  12. The current Chief of Army Staff, General Dalbir Singh Suhag is also from the Gorkha Rifles. He was commissioned in 4/5 GR in 1974. And according to the 5 GR tradition, he wears his head gear with the strap below the lower lip. Other GR units wear the chin strap below the jaw.

President of India inaugurates Golden Jubilee Celebrations of India’s first historic climb of Mt. Everest in 1965

The President of India, Shri Pranab Mukherjee inaugurated the Golden Jubilee Celebrations of India’s first historic climb of Mt. Everest in 1965 organized by The Indian Mountaineering Foundation today (May 20, 2015) at Rashtrapati Bhavan.

Speaking on the occasion, the President said that over the years Indian mountaineers have distinguished themselves not only by scaling the highest peaks but also as brave soldiers of the gallant armed forces which have included the ITBP. Many of them have served with great distinction during the Kargil conflict and continue to defend our highest frontiers with courage and with fortitude. Along with these great achievements, the first Indian conquest of Everest and the conquest by first Indian woman, Bachendri Pal, has found its place in many text books and has inspired several generations over the years.

The President said that the Indian Mountaineering Foundation that sponsored the Expedition in 1965 has come a long way since then and has grown to become an Institution that all adventure lovers look up to for guidance. It has always taken a broad and holistic approach in its mandate. In recent years the Indian Mountaineering Foundation has also been involved in environment protection works in the Himalayas. There is no greater service that it can do to this cause than by working for the preservation of the Himalayan ecology and the environment of the Himalayas. He expressed happiness over the fact that from very early on the mountaineering fraternity has encouraged women to take up this sport.

The President extended his greetings and felicitations to all surviving members of the historic expedition and paid homage to the memory of many courageous mountaineers of that expedition who are no longer with us today. He also paid homage to all those mountaineers who have lost their lives in their valiant attempts to climb Mt. Everest over the years. He wished members of the 1965 Everest Expedition, the Indian Mountaineering Foundation and the entire mountaineering community many years of productive contributions in the service of the nation. He stated that they have an important role to play in instilling in our youth the values and the character that make a good mountaineer and thereby a good citizen of our republic.

PM Modi on Three Day Visit to China: In Detail

Prime Minister Narendra Modi visited China this week to build friendship between the two Asian giants despite a long history of disputes and rivalries, along with some areas of cooperation, especially in the economic sphere.

PM Narendra Modi "believes" that his three-day visit to China will deepen bilateral ties and create a milestone for the relations between developing countries in Asia and around the world.
DAY 1
PM Modi’s first leg of his high-octane China visit in Xian promised a rich harvest of positive optics as Chinese President Xi Jinping went on record as saying that Modi was the first foreign leader whom he had received in his home province Xian. Mr. Modi has been given a traditional welcoming ceremony. It came as a reciprocation of sorts since Xi himself had begun his maiden India trip eight months ago in Ahmedabad, in Modi’s native state Gujarat.
"You received me very warmly in your hometown. I am very glad to receive you in my hometown," Xi told Modi in Chinese. Modi, in Hindi, responded, "This is an honour to 125 crore Indians whom I am representing as Prime Minister."
After their meeting, Xi Jinping accompanied Modi to several ancient sites in Xi'an. He also hosted a banquet for him in a building on the ancient city wall.
DAY 2
On the Day 2 of Modi's visit, India and China signed a record 24 agreements in key sectors, including in railways and education.

Protocol for setting up Consulates-General at Chengdu and Chennai besides an MoU on consultative mechanism for cooperation in trade negotiations were among the 24 agreements signed in the presence of Modi and his Chinese counterpart Li Keqiang.

DAY 3
On the third day of his visit to China, Prime Minister Narendra Modi met CEOs of top Chinese companies in Shanghai. Taking ties to a new level, 21 Memorandum of Understandings were signed between Indian and Chinese companies.

Modi who interacted with CEOs of 22 companies, invited them to participate in his 'Make in India' campaign and listed the 5F formula. He said, "I have come to say to you Make in India. The 5F Formula - From Farm to Fibre to Fabric to Fashion to Foreign! India and China can together give something to the world."

In a major takeaway, Bharti enterprises and IL&FS signed deals worth $2.5 billion and $3 billion respectively.
"In the three days that Prime Minister Narendra Modi has been in China, he has announced a slew of bilateral agreements — ranging from finding a political solution to the border issue, to strengthening cultural ties. We hope that this visit to one of the most powerful country in the world will be fruitful in both political and friendly manner."

Tiny dinosaur fossil discovered in China


Sheds new light on the evolution of flight
  • The fossil of a bizarre pigeon-sized dinosaur that had bat-like wings made of skin rather than feathers has been identified in China, shedding new light on the evolution of flight.
  • The dinosaur — named Yi qi — the shortest name ever given to a dino, which means “strange wing.”
  • At 160-million-years old, the dinosaur is older than the first known birds, such as Archaeopteryx. It also appears to be the earliest known flying non-avian dinosaur.

Unexpected discovery:

  • “This is the most unexpected discovery I have ever made, even though I have found a few really bizarre dinosaurs in my career,” paleontologist Xu Xing of the Institute of Vertebrate Paleontology and Paleoanthropology (IVPP) in Beijing said.
  • “It demonstrates how extreme the experimentation for dinosaurs to get in air is,” said Xu, the lead author of the study.
  • Researchers unearthed the remains for Yi qi at Hebei Province in China, Discovery Newsreported.
  • The rod-like bones that extended from each wrist of the tiny dinosaur and weighed about the same as a modern pigeon puzzled the scientists.
  • Their real purpose was determined by co-author Corwin Sullivan, a Canadian paleontologist now based at the IVPP, after he pored over scientific literature on flying and gliding animals.
  • Further investigation of Yi qi’s remains uncovered. While the dinosaur did have feathers, they were more like hairs, bristles or streamers, and would not have been capable of forming good aerodynamic surfaces, Sullivan said.
  • “Yi qi was mainly gliding, perhaps in combination with a bit of awkward flapping,” he added.
  • Researchers believe Yi qi was a scansoriopterygid, referring to a group of dinosaurs only known from China that were closely related to primitive birds.
  • The finding was published in the journal Nature .

All you need to know about Earthquakes (Nepal Updates)

For Recent Nepal Earthquake Updates [Part 1-26/04]: Click Here
For Recent Nepal Earthquake Updates [Part 2-12/05]: Click Here

What is an earthquake?

  • An earthquake is what happens when two blocks of the earth suddenly slip past one another. The surface where they slip is called the fault or fault plane. 
  • The location below the earth’s surface where the earthquake starts is called the hypocenter, and the location directly above it on the surface of the earth is called the epicenter.
  • Sometimes an earthquake has foreshocks. These are smaller earthquakes that happen in the same place as the larger earthquake that follows. Scientists can’t tell that an earthquake is a foreshock until the larger earthquake happens.
  • The largest, main earthquake is called the mainshock. Mainshocks always have after shocks that follow. These are smaller earthquakes that occur afterwards in the same place as the mainshock. Depending on the size of the mainshock, aftershocks can continue for weeks, months, and even years after the mainshock!


What causes earthquakes and where do they happen?
  • The earth has four major layers: the inner core, outer core, mantle and crust. 
  • The crust (Fig.2) and the top of the mantle make up a thin skin on the surface of our planet. But this skin is not all in one piece – it is made up of many pieces like a puzzle covering the surface of the earth. 
  • Not only that ((Fig. 3) ), but these puzzle pieces keep slowly moving around, sliding past one another and bumping into each other. We call these puzzle piecestectonic plates, and the edges of the plates are called the plate boundaries.
  • The plate boundaries are made up of many faults, and most of the earthquakes around the world occur on these faults. Since the edges of the plates are rough, they get stuck while the rest of the plate keeps moving.
  • Finally, when the plate has moved far enough, the edges unstick on one of the faults and there is an earthquake.


Why does the earth shake when there is an earthquake?
  • While the edges of faults are stuck together, and the rest of the block is moving, the energy that would normally cause the blocks to slide past one another is being stored up.
  • When the force of the moving blocks finally overcomes the friction of the jagged edges of the fault and it unsticks, all that stored up energy is released.
  • The energy radiates outward from the fault in all directions in the form of seismic waves like ripples on a pond. The seismic waves shake the earth as they move through it, and when the waves reach the earth’s surface, they shake the ground and anything on it, like our houses and us! (see P&S Wave inset)


How are earthquakes recorded?
  • Earthquakes are recorded by instruments called seismographs. The recording they make is called a seismogram.
  • The seismograph (Fig. 4) has a base that sets firmly in the ground, and a heavy weight that hangs free. When an earthquake causes the ground to shake, the base of the seismograph shakes too, but the hanging weight does not. Instead the spring or string that it is hanging from absorbs all the movement. The difference in position between the shaking part of the seismograph and the motionless part is what is recorded.


How do scientists measure the size of earthquakes?
The size of an earthquake depends on the size of the fault and the amount of slip on the fault, but that’s not something scientists can simply measure with a measuring tape since faults are many kilometers deep beneath the earth’s surface.

So how do they measure an earthquake?
  • They use the seismogram recordings made on the seismographs at the surface of the earth to determine how large the earthquake was (Fig. 5).
  • A short wiggly line that doesn’t wiggle very much means a small earthquake, and a long wiggly line that wiggles a lot means a large earthquake. The length of the wiggle depends on the size of the fault, and the size of the wiggle depends on the amount of slip.
The size of the earthquake is called its magnitude. There is one magnitude for each earthquake. Scientists also talk about the intensity of shaking from an earthquake, and this varies depending on where you are during the earthquake.

How can scientists tell where the earthquake happened?
(For more about P waves and S waves: Click Here)

  • Seismograms come in handy for locating earthquakes too, and being able to see the P wave and the S wave is important. You learned how P & S waves each shake the ground in different ways as they travel through it.
  • P waves are also faster than S waves, and this fact is what allows us to tell where an earthquake was.
  • To understand how this works, let’s compare P and S waves to lightning and thunder. Light travels faster than sound, so during a thunderstorm you will first see the lightning and then you will hear the thunder. If you are close to the lightning, the thunder will boom right after the lightning, but if you are far away from the lightning, you can count several seconds before you hear the thunder. The further you are from the storm, the longer it will take between the lightning and the thunder.
  • P waves are like the lightning, and S waves are like the thunder. The P waves travel faster and shake the ground where you are first. Then the S waves follow and shake the ground also. If you are close to the earthquake, the P and S wave will come one right after the other, but if you are far away, there will be more time between the two. By looking at the amount of time between the P and S wave on a seismogram recorded on a seismograph, scientists can tell how far away the earthquake was from that location. However, they can’t tell in what direction from the seismograph the earthquake was, only how far away it was. If they draw a circle on a map around the station where the radius of the circle is the determined distance to the earthquake, they know the earthquake lies somewhere on the circle. But where?
  • Scientists then use a method called triangulation to determine exactly where the earthquake was (Fig. 6). It is called triangulation because a triangle has three sides, and it takes three seismographs to locate an earthquake. 
  • If you draw a circle on a map around three different seismographs where the radius of each is the distance from that station to the earthquake, the intersection of those three circles is the epicenter!


How are quakes classified?

Based on their magnitude, quakes are assigned to a class. An increase in one number, say from 5.5 to 6.5, means that a quake's magnitude is 10 times as great. The classes are as follows:
  • Great: Magnitude is greater than or equal to 8.0. A magnitude-8.0 earthquake is capable of tremendous damage.
  • Major: Magnitude in the rage of 7.0 to 7.9. A magnitude-7.0 earthquake is a major earthquake that is capable of widespread, heavy damage.
  • Strong: Magnitude in the rage of 6.0 to 6.9. A magnitude-6.0 quake can cause severe damage.
  • Moderate: Magnitude in the rage of 5.0 to 5.9. A magnitude-5.0 quake can cause considerable damage.
  • Light: Magnitude in the rage of 4.0 to 4.9. A magnitude-4.0 quake is capable of moderate damage.
  • Minor: Magnitude in the rage of 3.0 to 3.9.
  • Micro: Magnitude less than-3.0. Quakes between 2.5 and 3.0 are the smallest generally felt by people.
After an earthquake strikes, its magnitude is continuously revised as time passes and more stations report their seismic readings. Several days can pass before a final number is agreed upon.


What are the seismic zones of India?
  • The Geological Survey of India (GSI.) first published the seismic zoning map of the country in the year 1935.
  • With numerous modifications made afterwards, this map was initially based on the amount of damage suffered by the different regions of India because of earthquakes.
  • Color coded in different shades of the color red, this map shows the four distinct seismic zones of India. Following are the varied seismic zones of the nation, which are prominently shown in the map:
Zone - II: This is said to be the least active seismic zone
Zone - III: It is included in the moderate seismic zone
Zone - IV: This is considered to be the high seismic zone
Zone - V: It is the highest seismic zone





Can scientists predict earthquakes?
  • No, and it is unlikely they will ever be able to predict them. Scientists have tried many different ways of predicting earthquakes, but none have been successful. On any particular fault, scientists know there will be another earthquake sometime in the future, but they have no way of telling when it will happen.
  • First, a statistical study of historical earthquakes in a given region shows how frequent quakes of various magnitudes have been in the past. From those figures, they can guess how likely future quakes will be. For example, if a certain region has been struck by four magnitude 7 quakes in the last 200 years, seismologists would say there is a 50 per cent probability of another such quake occurring in the next 50 years.
  • Seismologists can also measure how much stress a certain region of the earth's crust is under, and how quickly that stress is increasing. That knowledge, along with the elapsed time since the last earthquake, helps scientists determine if another earthquake is on the way. This method is far from perfect, though, and requires extremely detailed seismological data, which simply isn't available for most regions.


Is there such a thing as earthquake weather? Can some animals or people tell when an earthquake is about to hit?
  • These are two questions that do not yet have definite answers. If weather does affect earthquake occurrence, or if some animals or people can tell when an earthquake is coming, we do not yet understand how it works.
