ANCHORAGE (KTUU) - More than 80 earthquakes have hit southcentral Alaska since this morning’s 7.0 shaker. That 7.0 quake, centered across Cook Inlet from Eagle River, started a cluster of earthquakes centered between Knik-Goose Bay and Big Lake. The first two aftershocks measured 4.8 and 5.7 in magnitude, within just minutes of the first shaker. Just more than 10 minutes later, a 4.5 aftershock hit.
Within a half-hour, a 5.1-magnitude quake shook south of Big Lake. About an hour later a 4.9 shook, centered off Point Mackenzie Road.
