A tsunami warning that was issued for coastal zones in southern Alaska was cancelled and no tsunami was observed after back-to-back earthquakes measuring 7.0 and 5.7 magnitudes near Anchorage.

The warning went into effect for parts of the state’s Cook Inlet and southern Kenai peninsula minutes after the 7.0-magnitude earthquake rocked buildings in downtown Anchorage at 8:29 a.m. local time (9:29 a.m. PT). The warning was in place for 90 minutes before it was cancelled. Residents in low-lying areas went to higher ground during that period.

Emergency Management BC also said there was no tsunami threat to B.C.

The first quake in Alaska struck around 9:30 a.m. PT and the United States Geological Survey (USGS) says it was at a depth of 41  kilometres, about 13 km north of Anchorage. The magnitude size reported has ranged from 6.8 to 7.2, but the (USGS) last posted 7.0.

An aftershock registering a magnitude 5.7 hit about seven minutes later, nearly five kilometres northwest of Anchorage. There were then multiple aftershocks in the region, with one as high as 5.1-magnitude.

People were running out of buildings in Anchorage, and many have shown the damage caused by the quake on social media.

The Anchorage Police Department, which is operational after the earthquake, said they are handling multiple situations. The department said there is major infrastructure damage across the city and many homes and buildings are damaged. Many roads and bridges are also closed.

Residents are advised to stay off the roads if they don’t need to drive, seek shelter, check on relatives and friends if possible and only call 911 if it is an emergency.

There no immediate reports of any deaths or serious injuries.

Alaska Governor Bill Walker has issued a disaster declaration and says he has been in contact with the White House. An incident command center has been established at Joint Base Elmendorf.

Oak Bay police said watching and listening to video of the earthquake shows how frightening an earthquake can be and how little time there is when it happens.
