Alaska shaken by 194 earthquakes in 2 days

The 7.0 magnitude earthquake that caused serious infrastructure damage in and around Anchorage, Alaska, on Friday has been attended by at least 193 other quakes in the state over the course of two days, the U.S. Geological Survey reported Saturday.

Though tremors are common in Alaska, Friday's major quake was unusual. "It was very loud when it came," said Anchorage Mayor Ethan Berkowitz. "It was very clear that this was something bigger than what we normally experience."

No deaths have been reported in connection to the weekend's earthquakes, and the effects of the big one were likely muffled by its depth of about 25 miles below the surface.
