While most of us were sleeping last night:

A massive 8.8-magnitude earthquake struck Chile early Saturday, collapsing buildings, killing at least 16 people and downing phone lines. President Michele Bachelet declared a “state of catastrophe” in central Chile and said the death toll was rising. (AP)

As a result of the earthquake, there is the possibility of a tsunami striking Hawaii, with the first waves hitting around 4 EST.

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.

…A tsunami after a magnitude-9.5 quake that struck Chile in 1960, the largest earthquake ever recorded, killed about 140 people in Japan, 61 in Hawaii and 32 in the Philippines.

UPDATE (7 EST)– Hawaii was spared from a tsunami.
