2018-01-23 (IPMA)
At 09:31:40 UTC on January 23, 2018, an earthquake of magnitude M 7.9 (USGS source) occurred in the Gulf of Alaska near the Aleutian Islands, at a distance of about 290 km from Kodiak village, and about 1900 km NW of Vancouver, Canada. The estimated depth for the focus was 25 km. This event is located, in tectonic terms, near a subduction region, with high volcanic activity and also characterized by the occurrence of earthquakes of high magnitude. The strongest known earthquake occurred in the region on March 28, 1964 with a MW 9.2 magnitude, which caused a large tsunami that flooded areas up to a height of 68 meters (NOAA catalog).
A potential tsunami alert has been launched for the Pacific.
So far there are no reports of material or human damages. In macrosymic terms on the Mercalli Modified scale the intensity V was reached, which indicates possible very slight damages.
No significant replicates have been recorded so far.
