Chile quake spawns tsunami, threatens Pacific Rim: "A tsunami threatened nations around the Pacific Rim on Saturday, with an 8.8-magnitude earthquake off Chile sending potentially deadly waves across the ocean as fast as a jetliner.

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."
