“A powerful earthquake with a preliminary magnitude of 8.2 struck off the coast of Chile tonight, strong enough to be felt nearly 300 miles away in the Bolivian capital, and triggering a tsunami that has already started hitting the coastline.

The quake, which was centered 61 miles west-northwest of Iquique, Chile, and was 6.21 miles deep, was initially measured at 8.0, but was later upgraded, the U.S. Geological Survey said.

The Pacific Tsunami Warning Center said a six-foot tsunami that hit Pisagua, Chile, at 8:04 p.m. ET. There was some damage reported on roads linking northern towns between Iquique and Alto Auspicio, but it was immediately clear how much.

A tsunami alert was initially issued for Chile, Peru and Ecuador, but was later extended to Colombia and Panama. Tsunami watches were issued for Costa Rica, Nicaragua, El Salvador, Guatemala, Honduras and Mexico.

The warnings were later canceled for everywhere but Chile and Peru.

The shaking the quake caused in La Paz, Bolivia, was the equivalent of a 4.5-magnitude tremor, authorities there said.”

        VALUES ARE GIVEN IN BOTH METERS(M) AND FEET(FT).
 PER  - PERIOD OF TIME IN MINUTES(MIN) FROM ONE WAVE TO THE NEXT.

 NOTE - DART MEASUREMENTS ARE FROM THE DEEP OCEAN AND THEY
        ARE GENERALLY MUCH SMALLER THAN WOULD BE COASTAL
         MEASUREMENTS AT SIMILAR LOCATIONS.

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.
