ANCHORAGE, Alaska — Dozens of noticeable aftershocks above magnitude 4.0 are expected in the remote Aleutian Island region off Alaska in the days and weeks following a major 7.0 earthquake.
Alaska state seismologist Michael West says a dozen measurable aftershocks have already hit the region since Friday's quake, including one reaching 6.1 in strength.
None of the aftershocks are expected to cause a notable tsunami, since the initial quake did not cause one.
West says the Aleutian Island area is a major earthquake center, where temblors above magnitude 5.0 are felt every month.
The site of Friday's quake is quite active. West says significant quakes were felt just to the east and the west of Friday's earthquake in 1986 and 1996.
