7.2 magnitude quake rumbled across Alaska peninsula overnight, but No concerns noted for BC coastal regions

A 7.2 magnitude earthquake struck the Aleutian area of Alaska overnight

A significant earthquake was recorded along the Aleutian archipelago just before Midnight BC time on Saturday, a 7.2 magnitude event that briefly had Emergency Management officials awaiting updates on potential  Tsunami risk to the coastal areas of British Columbia.

The event which was centred near Sand Point Alaska was not near any of the major population centres for Alaska, with Anchorage some 611 miles to the east of it.

Still there were Tsunami warnings generated for the immediate coastal area of the Alaska Peninsula, the all clear coming a few hours after the seismic event, noting of just small measurements of tsunami activity.

The  first event of midnight,  has since generated small earthquakes in the same region for much of the morning.

For British Columbia, Provincial officials stood down on their concerns early in the event, that after an update from the American Tsunami Centre advised no risk and no Tsunami  Warnings would be generated here or for points further south.


The size of the quake has made for some Sunday morning news coverage for Alaska and beyond.
