The epicenter of Sunday's earthquakes
A series of strong earthquakes - the strongest two measuring 6.3 - has struck the North Pacific Ocean near Alaska's Adak Island, seismologists say. No tsunami warnings were issued and there were no immediate reports of damage.
The first earthquake happened at 9:57 a.m. local time on Sunday when a 6.3-magnitude earthquake struck about 70 miles (113 km) southwest of Adak Island, which is part of the Andreanof Islands group of the Aleutian Islands.
Adak Island, with a population of about 300 people, is nearly 1,200 miles southwest of Anchorage.
After several aftershocks, a second 6.3-magnitude earthquake hit the same area at 3:15 p.m. local time. This was followed by another series of aftershocks, including a 6.1 at 3:38 p.m., according to the U.S. Geological Survey (USGS).
