A huge and shallow earthquake shook up southeast Alaska late last night prompting the Tsunami Center to issue a tsunami warning for Alaska and Canada.

The quake, which occured at 11:58pm, registered a magnitude 7.5. It was located offshore 63 miles west of Craig, Alaska at a depth of 6.1 miles. The first, largest quake has been followed by at least nine other, smaller, quakes throughout the early Saturday morning hours.

Tsunami Alarms sounded throughout earthquake area and surrounding region, prompting people to move from the low-lying and coastal areas for a time. The tsunami warning covered approximately 700 miles of coastline in Alaska and Canada. It warned that “significant widespread inundation of land is expected.” The Tsunami Center would later amend their alert and report that the the waves generated by the earthquake were to small to pose a hazard. The estimated wave height for the tsunami was six inches.

Many of Sitka’s residents took refuge at the hign school there. In Craig, the community closest to the earthquake, several staging areas and shelters were made available.

The earthquake, while not causing any injuries, tossed items from shelves and knocked things from the walls. No other significant damage was reported.
