Himalayas poised for a series of big earthquakes, says study
The entire Himalayan arc is poised to produce a sequence of great earthquakes, and the next big quake -- of the magnitude of 8 or above -- may occur during our lifetimes, according to a study reviewing geological, historical, and geophysical data.
The study notes that the sequence of future Himalayan earthquakes could be similar to the great earthquakes that occurred in the twentieth century along the Aleutian subduction zone, which extends from the Gulf of Alaska to Kamchatka in Russian Far East.
Major cities along and close to the Himalayan frontal thrust include Chandigarh and Dehradun in India; and Kathmandu, Nepal.
Strong and damaging shaking in such great quakes could extend southward as far as India's capital, Delhi, one of the largest cities in the world with a population of more than 11 million, Wesnousky added.
