NEW DELHI, Sept. 20 (Xinhua) -- Indian scientists say the earthquake that hit the northeast Indian state of Sikkim and neighboring states of West Bengal Sunday is unusual in terms of its magnitude and nature of origin, and have warned of a major aftershock in the coming days, the Indo-Asian News Service Tuesday reported.|
The report quoted C.P. Rajendran, a scientist at the Indian Institute of Science, as saying while there is nothing surprising in this earthquake as the region north of Sikkim, which forms the outliers of Tibetan tectonics, and is known for moderate earthquakes in the past, what makes it different is its "unusually greater magnitude".
The quake is different from the usual Himalayan thrust earthquakes that are caused by the collision of the Indian plate with the Eurasian plate, he said.
Vineet Gahaulat, a scientist at the National Geophysical Research Institute in Hyderabad, was quoted as saying that the earthquake highlights the presence of the role of "transverse features in the Himalayas".
He said this 6.9 magnitude earthquake possibly occurred on a northwest-southeast trending, which scientists "generally do not expect in the Himalayas".
Gahaulat said the role of transverse features in segmenting the Himalayan arc and accommodating some of the convergence of the India-Eurasia plates is the likely cause of the quake.
He said he is also surprised at the few number of aftershocks -- only two to three aftershocks of magnitude greater than 4.5.
"We need to be careful" if, in the coming days, the aftershocks occur southeast of the main shock epicenter as the way two aftershocks have occurred... The region where the main shock occurred has very low population density, but further southeast, population density is higher," he was quoted as saying, in reference to the densely populated areas in West Bengal to the southeast.Indian scientists say sikkim quake unusual warn of aftershock - Pocket Hand WarmersIndian scientists say sikkim quake unusual warn of aftershock - Pocket Hand Warmers
