Alaska expecting 'noticeable' aftershocks

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, the Alaska state seismologist said Saturday.

A dozen measurable aftershocks have already hit the region since Friday’s quake, including one reaching 6.1 in strength, said seismologist Michael West. There have been more than 30 aftershocks measuring at least magnitude 2.5.

None of the aftershocks are expected to cause a notable tsunami, since the initial quake did not cause one. And West said experts are not too worried this quake will trigger another significant quake nearby in the near future.

“This is very common area for earthquakes,” West said. Temblors above magnitude 5.0 are felt every month.

The site of Friday’s quake is quite active. Significant quakes were felt just to the east and the west of Friday’s earthquake in 1986, 1996 and 2003.
