abstract An earthquake of MS = 6.3 occurred on 20 January 1982 near the east coast of Great Nicobar Island (in the Bay of Bengal), India and caused great panic among the inhabitants. Ground Fissures and damage to civil engineering structures was also caused. A study comprised of the recording of aftershocks and their migration, the preparation of an isoseismal map, and the compilation of other damage data is presented. Some recommendations have been made to permit suitable safeguards in future development.

Magnitude Estimates

abstract Isoseismal map measurements and magnitudes of several recent central and northeastern North American earthquakes are related by multiple regression analysis in order that mbLg magnitudes can be estimated for those noninstrumentally-recorded New England events whose total felt area is known to be ≧10,000 km2 and which occurred after 1727. Magnitude estimates of the noninstrumentally-recorded events permit New England seismicity to be studied on a basis other than the heretofore conventional maximum epicentral intensity approach.

Felt Area

abstract The magnitude 7.2 St. Elias earthquake of February 28, 1979 was felt over an area of about 500,000 km2 of Alaska, United States, and Canada. The maximum intensity was VII at Icy Bay Lumber Camp. No major damage resulted as the epicenter was in an unpopulated area of Alaska. Isoseismal maps are also presented for the earthquakes of September 4, 1899, September 10, 1899, 21 hr, October 9, 1900, and July 10, 1958; magnitudes 8.3, 8.6, 8.3, and 7.9, respectively. The felt areas of the 1899 and 1958 earthquakes were not significantly larger than the St. Elias felt area considering the uncertainty of their limit of perceptibility. The October 9, 1900 earthquake appears to be located in the Kodiak Island region and not near Cape Yakatage as previously published.

Information on the earthquake with Mw=5.4 that occurred on the southern coast of the Issyk-Kul lake on the southwestern slope of the Tegerek mountains (Kyrgyzstan) on November 14, 2014 is given. The epicenter is located in the Jumgalo-Terskey zone, identified as the Tonsky block, in which felt earthquakes with intensity up to 7 have occurred repeatedly. 231 aftershocks were recorded in the first day, in the second day – 13 aftershocks, then seismic activity decreased. Most of the aftershocks are localized in the depth range of 17–21 km, close to the depth of the main shock (h=20 km). The earthquake had the reverse fault type. Macroseismic survey was fulfilled only in the epicentral zone due to the complex weather conditions (late autumn, highlands). The theoretical isoseismal map was created for receiving the more complete picture of the earthquake impact outside of its epicentral zone.
