Ground Report | New Delhi: Earthquake in Jammu Kashmir increased; Witnessing many disasters ranging from devastating floods to devastating earthquakes, the vulnerabilities arising out of natural calamities in Jammu and Kashmir are constantly increasing. Intense cloudbursts, frequent flash floods, frequent landslides and avalanches pose a serious threat not only to the sustainable development of the state but also to human existence.
Why Earthquake in Jammu Kashmir increased
The earth is constantly shaking in Jammu and Kashmir and Ladakh. In the last month six earthquake tremors of magnitude 3 to 4 in both states. The geological movement, including the past history and earthquake trends in recent decades, poses a risk of major earthquakes.
Experts believe that being in the category of seismic zones 4 and 5, earthquakes of magnitude 8 or more cannot be ruled out in Jammu and Kashmir in future.
As per the report of Amar Ujala, GM Bhatt, Professor, Department of Geology, University of Jammu, says that the Main and Central Boundary Thrust is active in Jammu and Kashmir. The Main Boundary Thrust starts from the Jammu division till Himachal and Central Boundary Thrust runs from the Ramban district to Himachal.
The damage caused by an earthquake depends on the geographical location of the area of its impact. In 2013, a 5.7 magnitude earthquake struck Kishtwar, but geographically, about 46,000 small and large construction structures were damaged there. In Jammu and Kashmir, earthquakes of 6.2 magnitudes occurred in 1885, 7.6 in 2005 and 8 in 1555.
According to a 2015 study, a major earthquake of magnitude 8 or more could strike Jammu and Kashmir, threatening the lives of one million people, according to the latest geologic mapping of the state’s Himalayan mountains.
Scientists found that the Reasi Fault has been building pressure for some time, suggesting that when it releases or “slips”, the resulting earthquake could be large – as high as magnitude 8.0 or greater.
“We set out to learn how much the fault has progressed over the past tens of thousands of years, when it moved, and how the different sections of the fault progressed,” said study lead author Yann Gavilot. Worked as a doctoral student at Oregon State University in the US.
“What we found was that the Reasi fault is one of the main active faults in Kashmir, but the recent geologic record lacks earthquakes.
“The fault hasn’t slipped in a long time, which means the potential for a major earthquake is strong. Whether it’s going to happen is not a question. It’s a matter of when,” Gavilot said. There is direct evidence of some seismic activity on the fault, where researchers could see the displacement of the Earth where the earthquake lifted a portion of the fault five or more meters – possibly about 4,000 years ago, the researchers said, before written records from local monasteries last. refer to strong ground shaking over several thousand years.
