Alaska's Kodiak Island is being slammed by a swarm of earthquakes -- one with a magnitude of at least 5.9.
Richard Buckmaster, a geophysicist at the National Earthquake Information Center in Golden, Colo., says the southeast region of the island was hit Saturday by 20 earthquakes with magnitudes of 2.6 or greater.
He says the 5.9-magnitude quake is expected to be upgraded to 6.1.
The quakes are centered southeast of Old Harbor, but there have been no reports that they've been felt. The earthquakes follow two light quakes that struck the same area less than an hour apart Friday.
