earthquake in Alaska map
A 6.3-magnitude earthquake has struck in Alaska, some 42 miles southwest of the active Redoubt Volcano, the US Geological Survey (USGS) has said.

Notably, the earthquake also struck near Mt. Katmai, the site of the largest volcanic eruption of the 20th century.

The epicenter was 9 miles south of Mt. Iliamna, another volcano in the area, the Alaska Dispatch News reported.

According to the USGS, the quake hit about 141 miles southwest of Anchorage.

The agency is forecasting "very light damage."

The earthquake was originally reported as having a magnitude of 6.2, but was later revised up slightly.

USGS reported two minor tremors prior to the 6.3 magnitude one.

Although the quake did not strike far from the Redoubt Volcano, there's nothing to suggest activity has been triggered by the quake.

There have been four confirmed eruptions at the volcano since the 20th century began, in 1902, 1966, 1989 and 2009.
