The center says the Thursday evening quake was felt through the central Aleutians and as far east as Dutch Harbor and Unalaska. There are no immediate reports of damage.
The West Coast and Alaska Tsunami Warning Center posted a tsunami warning for certain coastal areas of Alaska, but canceled the warning about an hour after the quake. The warning covered an area from 80 miles northeast of Dutch Harbor to about 125 miles west of Adak.
In Dutch Harbor, longshoreman Jim Paulin said warning sirens caused hundreds of people to begin climbing up a nearby hill.
