The entire Himalayan arch is set to form one order of the great earthquake, and the next major earthquake – of magnitude 8 or greater – may occur during our lifetime, according to a review of geological, historical and geophysical data. Researchers said the human toll of such an event in densely populated countries is likely to be unprecedented. The study notes that the order of future Himalayan earthquakes may be similar to the great twentieth-century earthquakes along the Aleutian subduction zone, extending from the Gulf of Alaska to Kamchatka in the Russian East.
In a review published in August in the journal Seismological Research Letters, basic geological principles — stratographic analysis, structural analysis, soil analysis, and radiocarbon analysis — were used to estimate the size and timing of prehistoric earthquakes and evaluate future risks. The study’s author, Steven G. Wessonsocki, told RTI, “It has been the source of a completely great earthquake stretching from the eastern border of Arunachal Pradesh (India) in the east to Pakistan (in the west).” “These earthquakes will come again and scientifically, it would be no surprise if the next great earthquake occurred in our lifetime. But the determination of our studies is the best on the order of 100 years long from human life, ”said Wesnowski, director of geology and seismology at the University of Nevada and the Center for Neotectonic Studies at the University of Reno, USA.
Seismologist Supriyo Mitra said the research matches previous studies. “The research is a comprehensive review of forecasts of future events based on predictive studies and findings of past Himalayan earthquakes,” said Professor Mitra in the Department of Earth Sciences at the Indian Institute of Science Education and Research (IISER). Kolkata. “Himalayan faults, as shown in the paper, are designed to produce earthquakes of magnitude 8-plus. So yes, we are staring big in the future. How can anyone tell so far, ”Mitra, who was not involved in the study, told PTI. Prior studies have investigated the rate of stress accumulation that occurs along the Himalayan arc from satellite accumulation.
In the latest study, the timing and size of recent prehistoric earthquakes were defined by geology. The methodology directly applies geodynamic principles to define the past size and time of earthquakes as recorded by broken and deformed deformations by earthquake centers at sites along the length of the Himalayan frontal thrust. He said that the satellites can help in locating the location of active earthquake faults but are unable to provide any information about the past time and size of the earthquake on those faults. “These observations taken together tell us that enough earthquakes observed in the geologic record have again caused enough tension along the entire arc,” Wesnowski reported. Cities along and adjacent to the Himalayan frontal region include Chandigarh and Dehradun in India; And Kathmandu, Nepal.
Wesneski said that such magnificent lakes could have a strong and damaging south India extending to India’s capital Delhi, one of the largest cities in the world. North India has witnessed several earthquakes of small earthquakes in the last four months, causing a huge speculation in the region. However, he said, scientists have yet to find a systematic relationship between the occurrence of small earthquakes and the timing of large earthquakes in the future. He said, “These small earthquakes are thousands of times smaller than the great earthquakes we are studying.”
