Alaska still shaking with aftershocks from 7.0 earthquake
On Friday, November 30, a magnitude 7.0 earthquake struck Anchorage, Alaska. The initial jarring was destructive - and now, more than a month later, daily jolts continue to leave residents shaken.
Since the main shaking, about 350 aftershocks of magnitude 3 or greater have been registered on seismometers. Some - including the five 5.0 or worse quakes - have been large enough to cause additional damage. Though the aftershocks have slowly been winding down, the magnitude 5.0 tremor on Jan. 1 and magnitude 4.2 on Wednesday show that Alaskans are far from out of the woods yet.
That begs the question - how long will the earthquakes continue? We can turn to a little bit of seismology for the answer....
