Earthquakes unveil deep rock structure under East Asia

May 15, 2015

Washington, May 15: Scientists have found a towering rock structure deep under East Asia by using 3-D supercomputer simulations of data from 227 earthquakes that hit the region during 2007-2011.

The finding could throw light on the fate of the subducted continental plates beneath the Tibetan Plateau, known as ‘the roof of the world,’ which rises about 5km above sea level.

The work may also help find hidden hydrocarbon resources, and more broadly it could help explore the Earth under East Asia and the rest of the world, researchers said.

“We are combining different kinds of seismic waves to render a more coherent image of the Earth,” said principal investigator and lead author Min Chen from the Rice University.

Researchers combined seismic records from thousands of stations for each earthquake to produce scientifically accurate, high-resolution 3-D tomographic images of the subsurface beneath immense geological formations.

Like a thrown pebble generates ripples in a pond, earthquakes make waves that can travel thousands of miles through the Earth.

A seismic wave slows down or speeds up a small percentage as it travels through changes in rock composition and temperature.

The scientists mapped these wave speed changes to model the physical properties of rock hidden below ground.

“We found that beneath the Tibetan plateau, the world’s largest and highest plateau, there is a sub-vertical high velocity structure that extends down to the bottom of the mantle transition zone,” the principal investigator said.

The bottom of the transition zone goes to depths of 660 kilometres, she said.

“Three-dimensional geometry of the high velocity structure depicts the lithosphere beneath the plateau, which gives clues of the fate of the subducted oceanic and the continental parts of the Indian plate under the Eurasian plate,” she added.

The research was published in the Journal of Geophysical Research, Solid Earth.

Jan 18: To mark the 30th anniversary of the mass exodus of Kashmiri Pandits from the Valley, members of the community took to social media to post videos of themselves by narrating the "Hum Aayenge Apne Watan" dialogue from an upcoming flick, 'Shikara', with the hope that they would return to their homeland one day.

On January 19, 1990, lakhs of Kashmiri Pandits were forced to leave their homes in the Valley following a genocidal campaign launched by the terrorists.

Theatre actor Chandan Sadhu participated in the campaign and said that Kashmiri Pandits have shown "unimaginable resilience" and hope to return to the Valley soon.

"As Kashmiri Pandits complete 30 years in exile this weekend, let our cry for justice be finally noticed. We have shown unimaginable resilience, and today we resolve to return home. Kashmiri Pandit friends: please record this video statement and put it up with #HumWapasAayenge," Sadhu tweeted.

The #HumWapasAayenge is trending on Twitter as more and more Kashmiri Pandits joined in the campaign to narrate the "Hum Aayenge Apne Watan" dialogue and a pledge to return to their homes.

Noted political commentator Sunanda Vashisht tweeted a throwback image of herself and said that resolve to go back home has strengthened more.

"I don't have many pictures left of my childhood. Choosing between life and family albums is really no choice at all. When lives were rescued, family albums got left behind. 30 years have passed. Resolve to go back home has only strengthened. #HumWapasAayenge," she tweeted.

Radio personality Khushboo Mattoo tweeted a video repeating the dialogue from Shikara and tweeted, "Said this in a BBC interview three years back. And I am saying it again #HumWapasAayenge #Shikara."

Journalist Rahul Pandita also took to his Twitter and captioned his post saying, "30 years of exile from Kashmir. Let us now pledge that we will return home."

'Shikara' chronicles the exodus of Kashmiri Pandits from the Valley on the night of January 19, 1990. Helmed by Vidhu Vinod Chopra, the movie is slated to release on February 7.

Netizens have supported the initiative and have expressed solidarity with the Kashmiri Pandits.

In July last year, Home Minister Amit Shah said in the Rajya Sabha that the central government is committed to bringing Kashmiri Pandits and Sufis back to the Valley saying a time will come when they will offer prayers at the famous Kheer Bhawani temple.

"Kashmiri Pandits were forced to leave Kashmir. Many of their shrines were demolished. Sufism was targeted in Jammu and Kashmir. Sufism used to talk about unity and harmony but they were attacked. No voice was raised in favour of Kashmiri Pandits and Sufis when they were brutally attacked. Sufis used to talk about the unity among Hindus and Muslims but they were forced to leave the Valley. Narendra Modi-led government is committed to bringing back Kashmiri Pandits, he had said.

The Mata Kheer Bhawani temple is one of the holiest shrines of Kashmiri Pandits, located about 14 kilometres east of Srinagar.

Last September, a delegation of the Kashmiri Pandit community met the Prime Minister in Houston and thanked him for the historic decision to abrogate Article 370 that gave special status to Jammu and Kashmir.

Modi acknowledged the hardships endured by the community following their exodus from their ancestral homeland back in 1989-1990 due to militancy.

"You have suffered a lot, but the world is changing. We have to move ahead together and build a new Kashmir," the Prime Minister had told the delegation.

"I had a special interaction with Kashmiri Pandits in Houston," Modi had tweeted following the interaction.

In October, Union Minister Prakash Javadekar announced that the Centre has decided to provide compensation of Rs 5.5 lakh each to 5,300 displaced families from Pakistan-occupied Kashmir (PoK), who initially opted to move outside Jammu and Kashmir but later on returned.

These families were earlier left out in the rehabilitation package that was approved by the Cabinet on November 30, 2016.

The Prime Minister had announced a reconstruction plan for Jammu and Kashmir in November 2016. His plan included a rehabilitation package for a one-time settlement of 36,384 displaced persons' (DPs) families of PoK-1947 and Chhamb.

Jun 23: The U.S. government on Monday restricted charter flights from India, accusing the nation of "unfair and discriminatory practices" by violating a treaty governing aviation between the two countries.

Air India Ltd. has been making flights to repatriate its citizens during the travel disruptions caused by the Covid-19 outbreak, but also has been selling tickets to the public, the Transportation Department alleged.

At the same time, U.S. airlines have been prohibited from flying to India by aviation regulators there, the DOT said in its order. The situation "creates a competitive disadvantage for U.S. carriers," the agency said in a press release.

Air India is advertising a schedule that is more than half of pre-virus operations, the department said. "The charters go beyond true repatriations, and it appears that Air India may be using repatriation charters as a way of circumventing" that nation's flight restrictions, the U.S. agency said.

The order becomes effective in 30 days, the department said.

Indian airlines must apply to the DOT for authorization before conducting charter flights so that it can scrutinize them more closely, it said. The department will reconsider the restrictions once India lifts restrictions on U.S. carriers.

The action against India follows weeks of DOT restrictions against Chinese airlines after the U.S. agency accused that nation of unfairly banning American carriers in the wake of the virus. On June 15, the U.S. announced it would agree to allow four flights a week from China after it allowed the same number by U.S. carriers.

Attempts to reach Air India and the Indian embassy in Washington after business hours were unsuccessful.

New Delhi, Jan 9: Amazon founder and CEO Jeff Bezos will be visiting India next week and is likely to meet Prime Minister Narendra Modi and officials, besides industry leaders, according to sources.

The top executive will also attend SMBhav – an event focussing on small and medium businesses in India - that is slated for January 15-16 in the capital city.

When contacted, Amazon declined to comment.

Amazon, which has seen significant growth in its business in India, has also witnessed protest from a section of traders in the country who claim that e-commerce giants including Amazon and Walmart-owned Flipkart offer deep discounts and engage in unfair business practices.

Last year, the government had tightened rules for e-commerce marketplaces with foreign investment. These rules barred such platforms from offering products of sellers in which they hold a stake and banned exclusive marketing arrangements among other clauses. Following this, Amazon restructured its joint ventures to ensure compliance.

Bezos is likely to discuss regulatory issues in his meeting with the government officials.

He is also slated to engage with SMBs during the SMBhav event. The event - which will focus on discussions around how technology adoption can enable SMBs in India - is slated to see participation from industry experts, policymakers, solution providers and Amazon leadership.
