A huge earthquake (8.8 magnitude) rocked Chile this morning, resulting in a tsunami that is threatening the entire Pacific rim including the Oregon coast. From the O:

Experts warned that a tsunami could strike anywhere in the Pacific, and Hawaii could face its largest waves since 1964 starting at 11:19 a.m. (4:19 p.m. EST, 2119 GMT), according to Charles McCreery, director of the Pacific Tsunami Warning Center.

Tsunami waves were likely to hit Asian, Australian and New Zealand shores within 24 hours of the earthquake. The U.S. West Coast and Alaska, too, were threatened.

From the AP:

A tsunami warning — the highest alert level — was issued for Hawaii, where emergency officials planned to wake residents with sirens alerting them to the impending waves. Even before daybreak, lines formed at supermarkets with residents stocking up on water, canned food and batteries. Cars lined up 15 deep at several gas stations.

The first waves were expected at 11:19 a.m. Saturday (4:19 p.m. EST). Most Pacific Rim nations, awaiting further data, did not order evacuations but advised people in low-lying areas to be on the lookout.

Ecuadorean President Rafael Correa told the Ecuavisa channel that a tsunami has passed the Galapagos Islands, causing a swell but no damage.

Unlike other tsunamis in recent years, emergency officials along the Pacific have hours to prepare and possibly evacuate residents.
