An earthquake rumbled last night in Southern Alaska.

It occurred at 10:13 p.m. on August 11, Anchorage time (11:13 p.m., Vancouver time).

The U.S. Geological Survey measured it as a 4.2-magnitude quake while the Alaska Earthquake Center listed it as a 4.3-magnitude temblor.

At a depth of 44 kilometres (27 miles), the epicentre was located 31 kilometres (19 miles) northwest of Willow, Alaska; 65 kilometres (40 miles) northwest of Knik-Fairview, Alaska; 82 kilometres (51 miles) northwest of Anchorage, Alaska; and 838 kilometres (519 miles) west of Whitehorse, Yukon.

On July 29, a powerful 8.2-magnitude undersea earthquake struck off the Alaskan Peninsula coastline. A tsunami alert for Southern Alaska had been issued but was later called off.
