The big blue box in the center of the map represents a 5.4 magnitude earthquake that shook Southcentral AK yesterday at 11:28 a.m. The Anchorage Daily News reports that the region gets about one or two earthquakes this size each year. Ian, a friend who lives in Anchorage and works a graveyard shift sent me a text saying that the quake woke him up. Aside from rousing Ian, hanging lamp shades swung in Anchorage, though no damage was reported. Yesterday's quake originated on the Denali fault line, the same fault that produced a 7.9 magnitude quake in 2002.About nine hours later two distinct quakes, a 5.5 and 5.4 shook the western Aluetian Islands.
