An earthquake similar in magnitude to the one that hit Turkey is “imminent” in the fault lines of the Uttarakhand region and can happen “any time”, chief scientist of seismology at the National Geophysical Research Institute (NGRI), Dr N Purnachandra Rao, has warned.
In the Himalayan region, which stretches from Jammu and Kashmir to Arunachal Pradesh, an earthquake of 8-plus magnitude is likely to occur, Dr N Purnachandra Rao, has warned.
Rao told TOI that a lot of stress is building up beneath the surface in the Uttarakhand region, and a “great earthquake” is inevitable to release the stress. He, however, added that the date and time of the quake cannot be predicted, and the devastation would depend on multiple factors which vary from one geographic area to another.
We have set up around 80 seismic stations in the Himalayan region focused on Uttarakhand. We are monitoring the situation real-time. Our data shows stress accumulating big time,” he added. “We have GPS networks in the area. GPS points are moving, indicating changes happening beneath the surface.”
Rao said variometric GPS data processing is one of the reliable methods to determine what’s happening with the earth. “We cannot predict the exact time and date, but Uttarakhand will witness a massive earthquake any time,” Rao insisted. Variometers measure variations in the Earth’s magnetic field.
The comments by the top scientist come in the backdrop of ground subsidence in Joshimath, considered the gateway to pilgrim sites like Badrinath and Kedarnath. Also, the Char Dham Yatra, which brings lakhs of pilgrims to the Uttarakhand mountains, is set to start in about two months.
Earthquakes of magnitude 8 and above are called “great earthquakes”. “Turkiye witnessed a 7.8 magnitude earthquake,” he said. “Technically, it cannot be called a great earthquake. But the devastation was high in Turkiye due to multiple factors, including poor quality construction.”
