ANCHORAGE - A large earthquake of 7.0 magnitude struck the ocean 57 miles (92 km) off the remote Alaska island of Adak early Friday, according to the US Geological Survey.
There were no initial reports of damage, and the West Coast and Alaska Tsunami Warning Center said there was no tsunami watch, warning or advisory in effect.
"At this point, we've seen no ocean-surface disturbance," said Bill Knight, a scientist at the tsunami warning center in Palmer, Alaska. While no tsunami was expected, he said scientists were still monitoring the area for any earthquake-induced waves.
Knight cited callers from Atka, a tiny Aleutian Island village 65 miles northeast of the quake's center that is home to 61 residents, as saying there was "strong shaking" but no damage.
Scientists at the tsunami warning center were still waiting on Friday morning for reports from Adak, Knight said.
Adak, about 1,300 miles southwest of Anchorage, has 321 residents, according to state records.
