A lot of aftershocks after the big 7.0 earthquake in Alaska

More than 1,000 aftershocks followed until Sunday following the strong 7.0 magnitude degrees earthquake which occurred Friday centered 10 miles northeast of Anchorage.

But more than 350 of the aftershocks were higher than 2.5, according to USGS data. A 5.2 aftershock about 11 p.m. Friday was the second-biggest since a 5.7 temblor hit minutes after the main quake. "This is the second-largest earthquake we've had since 1964, which was a very significant earthquake," Anchorage Mayor Ethan Berkowitz told reporters Saturday, referring to the 9.2 quake that was the most powerful recorded in US history. No fatalities or serious injuries however were reported, officials said. In Alaska's largest city, Anchorage, with a population of about 300,000 , airports, hospitals, emergency services and most businesses were operating. "The power is up. The heat is on. The communication lines are opening," said Anchorage Municipal Manager Bill Falsey.


The earthquake was not unusual for the region. "It just didn't stop. It kept going and got louder and louder,” a resident described. Major infrastructure damages occurred. Alaska Regional Hospital and Providence Alaska Medical Center suffered damage. The Anchorage School District canceled classes Monday and Tuesday. The 7.0 earthquake was felt up to 400 miles away.
