ANCHORAGE, Alaska — Several aftershocks rattled a remote Aleutian Island region off Alaska in the hours after a major 7.0 temblor struck with a jetlike rumble that shook homes and sent residents scrambling for cover.

At least three dozen aftershocks, including one reaching magnitude 6.1 in strength, struck after the major quake Friday, according to the U.S. Geological Survey.

“I heard it coming,” said Kathleen Nevzoroff, who was sitting at her computer in the tiny Aleutians village of Adak when the 7.0 temblor struck at 8:25 a.m., getting stronger and stronger. “I ran to my doors and opened them and my chimes were all ringing.”

There were no reports of damage or injuries from the earthquake, which occurred in a seismically active region.
