Earthquake Strikes Off West Coast Of Alaska

An earthquake measuring 7.7 has been recorded in the Pacific Ocean off Alaska.
The quake was centred about 60 miles (100 km) southwest of Port Alexander at a depth of about six miles (10km), according to the US Geological Survey.
The Alaska Tsunami Warning Centre says some areas are seeing small sea level changes, but there will be no widespread destructive wave that had earlier been warned about.

Interior Alaska has experienced numerous small quakes during the past few weeks, which isnโ€™t unusual. Many residents felt the magnitude 3.4 quake at about 11:15 p.m. on Dec. 18. The quake was centered near Minto, about 40 miles northwest of Fairbanks.
These smaller quakes donโ€™t often predict larger quakes in the near future. They can serve as a reminder of the ever-present possibility, though.
The Alaska Range on our southern horizon is jagged for a reason – the peaks are still being uplifted by tectonic activity. On Nov. 3, 2002, an earthquake of 7.9 magnitude hit in the center of the mountains straight south of Fairbanks. It was the largest inland quake in North America during the previous 150 years. In some locations, ground on each side of the Denali Fault came to rest offset by as much as 13 feet vertically and 28 feet horizontally.
