EVALUATION

SEA LEVEL READINGS INDICATE A TSUNAMI WAS GENERATED. IT MAY HAVE
BEEN DESTRUCTIVE ALONG COASTS NEAR THE EARTHQUAKE EPICENTER AND
COULD ALSO BE A THREAT TO MORE DISTANT COASTS. AUTHORITIES SHOULD
TAKE APPROPRIATE ACTION IN RESPONSE TO THIS POSSIBILITY. THIS
CENTER WILL CONTINUE TO MONITOR SEA LEVEL DATA TO DETERMINE THE
EXTENT AND SEVERITY OF THE THREAT.

FOR ALL AREAS - WHEN NO MAJOR WAVES ARE OBSERVED FOR TWO HOURS
AFTER THE ESTIMATED TIME OF ARRIVAL OR DAMAGING WAVES HAVE NOT
OCCURRED FOR AT LEAST TWO HOURS THEN LOCAL AUTHORITIES CAN ASSUME
THE THREAT IS PASSED. DANGER TO BOATS AND COASTAL STRUCTURES CAN
CONTINUE FOR SEVERAL HOURS DUE TO RAPID CURRENTS. AS LOCAL
CONDITIONS CAN CAUSE A WIDE VARIATION IN TSUNAMI WAVE ACTION THE
ALL CLEAR DETERMINATION MUST BE MADE BY LOCAL AUTHORITIES.

ESTIMATED INITIAL TSUNAMI WAVE ARRIVAL TIMES AT FORECAST POINTS
WITHIN THE WARNING AND WATCH AREAS ARE GIVEN BELOW. ACTUAL
ARRIVAL TIMES MAY DIFFER AND THE INITIAL WAVE MAY NOT BE THE
LARGEST. A TSUNAMI IS A SERIES OF WAVES AND THE TIME BETWEEN
SUCCESSIVE WAVES CAN BE FIVE MINUTES TO ONE HOUR.

美國地質調查所（USGS）說，智利北部今天發生規模7.6強震，為了以防萬一，已下令北部沿岸居民緊急疏散。

A massive earthquake shook the coast of northern Chile on Tuesday night, setting off small landslides and a tsunami and killing at least five people. But scientists say the quake was not the "big one" that is predicted for the region.

Massive Chile Earthquake May Not Be the "Big One"
Scientists don't know when a possible larger quake might strike along the subduction zone, an area where one tectonic plate slides beneath another.

地牛又翻身，智利昨天才傳出8.2的強震，台北時間今天上午7點22分，日本也發生規模5.3的地震。

這起地震震央位在岩手縣沿岸南部，包括311重災區大船渡和宮城縣的登米市，最大震度都有4。

當局已經發布海嘯警報，而稍早智利強震引發的海嘯，也在清晨5點多陸續抵達日本東北，目前測得的海嘯高度，以岩手的40公分最大，不過當局預測海嘯最大高度可能達到1公尺，提醒沿岸民眾注意。

至於這起5.3地震，目前尚未傳出重大災情。
