1881 Nicobar Islands Earthquake (Paperback)

High Quality Content by WIKIPEDIA articles! The 1881 Nicobar Islands earthquake occurred at about 07:49 local time (01:49 UTC) on 31 December, with an epicenter beneath Car Nicobar. It occurred as two separate ruptures, the largest of which had an estimated magnitude of 7.9 on the moment magnitude scale and triggered a tsunami that was observed around the Bay of Bengal. It is probably the earliest earthquake for which rupture parameters have been estimated instrumentally. The Andaman and Nicobar Islands suffered some damage, although the only masonry buildings affected were in Port Blair, including an infantry barrack and a chimney, both of which suffered severe cracking. On Car Nicobar the coconut plantations and native huts were extensively damaged and sand volcanoes were observed. There were no reported casualties associated with either the earthquake or the subsequent tsunami.
