The southern Kenai Peninsula got a shake up Thursday evening at 9:25 pm.

A 4.3 magnitude eartthquake struck on the southern tip of the peninsula this evening approximately 27 miles to the southwest of Homer. The quake occurred at a depth of 33.8 miles.

No damage occurred during the quake that lasted less than a minute.

The quake occcurred at the eastern end of the Aleutian arc that runs across the northern edge of the Gulf of Alaska all the way to the Kamchatka Peninsula. The full extent of the Aleutian arc is a very seismically active region and quakes are occuring all along the whole region daily.

It is in this arc that the Pacific plate subducts under the North American plate and is responsible for the numerous volcanoes that dot the region from Cook Inlet all the way to Asia.
