This is the third moderate earthquake (M>5) along the
Myanmar-Manipur border since 11 August 2009. The latest event is
also the strongest earthquake in this immediate region since a
Mw=5.7
earthquake on 18 September 2005 that caused some damage in Manipur,
India, and was widely felt across the region. Earthquakes are not
uncommon on the Manipur-Myanmar border or on the Nagaland-Myanmar
border. Significant M7+ earthquakes have been recorded in these
regions in 1869, 1880, 1920, 1932, 1938, 1954, 1970 and 1988. Due to
the depth of most of these, damage was minimal but they were felt
very widely in north-east and eastern India and in Bangladesh. The
1954 earthquake was felt as far as Khajurao in Madhya Pradesh,
India. The most destructive earthquake in this immediate region was
the Mw=7.4 Manipur-Cachar earthquake in 1869 that caused widespread
damage at Imphal and in the Silchar region besides causing panic as
far as Kolkata. |
