5.4-magnitude tremor recorded off the British Columbia coast

No reports of any damage.

The quake off Vancouver Island struck just a minute before a smaller 2.8-magnitude natural disaster hit approximately 22 miles southwest of Neah Bay and west of the Washington state coast.

"These are the style of earthquakes which can be very tsunami-producing", West said. Kodiak is a coastal city of around 6,000 on the northeastern part of Kodiak Island, around 250 miles southwest of Anchorage.

The Department of Public Safety says Unalaska is in the clear after a tsunami warning Tuesday night caused Unalaskans to evacuate to higher ground.

According to the U.S. Geological Survey, the 7.8 magnitude quake hit Tuesday night at 11:12 PM PST off the Alaska coast about 60 miles south-southeast of Perryville, Alaska at a depth of 6 miles.

In Kodiak, a high school was established as an emergency shelter as warnings urged people to move inland and seek higher ground. "I've been passing out masks since the first siren sounded". "We've got probably 300, 400 people all wearing masks".

The quake, which struck at 4:33 a.m. PDT on July 22, was centered just north of the 49th parallel, approximately 137 miles west of Tofino, B.C., according to information from the United States Geological Survey.

The 5.1 magnitude natural disaster struck at about 4:30 a.m. Wednesday. "These aftershocks will go and go and go and go".

Alaska is the most actively seismic state.

The Alaska-Aleutian Trench was also where a magnitude 9.2 quake in 1964 was centered.

While commonly plotted as points on maps, earthquakes of this size are more appropriately described as slip over a larger fault area. Almost 25,000 earthquakes have been recorded in Alaska since January 1, according to the center.
