Strong earthquake, initially registered as M 6.8 but later revised to M 6.4 struck Kuril Islands, Russia at 18:12:42 UTC on November 16, 2012 according to USGS. The epicenter was located 162 km (101 miles) SSW (198°) from Severo-Kuril’sk, Kuril Islands, Russia (49.200°N, 155.700°E) at depth of 4.9 km (3.0 miles) which was later changed to 29.1 km (18.1 miles).
