Dehradun: Since then, geologists have been warning of an imminent major earthquake in the Himalayan region. And now, a peer-reviewed study, recently published in the international journal “Tectonophysics,” confirms that a “destructive earthquake” may be imminent in the region since the last “big earthquake” occurred about 500 years ago, and a lot of tectonic energy has been accumulating in the region in the past five centuries. “With more than 500 years of quiescence since the last major earthquake in the central seismic divide, another devastating rupture could be imminent in this part of the Himalayan Thrust Front (HFT),” the study, which is titled “Late Medieval Earthquakes on the Fault.” HFT at Lal Dhang,” she said. The HFT is located on the active tectonic boundary between Eurasia and the Indian subcontinent and passes near the major cities of Uttarakhand such as Dehradun, Ramnagar, Rokri and Haridwar. The US City and Missouri Department of Natural Resources found that HFT experienced two consecutive large earthquakes, greater than magnitude 8, during the Late Medieval Period. Between 1317-1391 AD and 1447-1572 AD. To find evidence of past earthquakes in the HFT, the researchers excavated a trench at Lal Dhang, located 175km northeast of Delhi and 55km southwest of Dehradun, and found that “past earthquakes on the HFT led to significant ground displacement evidenced by large scraps along the The fault.” “The presence of large scraps along the fault indicates the destructive nature of the earthquake that would have occurred here,” said one of the study’s authors, adding that, “Should another earthquake of similar nature occur, towns along the HFT would likely face the burden the biggest “.
