AN EARTHQUAKE HAS OCCURRED WITH THESE PRELIMINARY PARAMETERS

ORIGIN TIME - 0546Z 11 MAR 2011

COORDINATES - 38.2 NORTH 142.5 EAST

DEPTH - 10 KM

LOCATION - NEAR EAST COAST OF HONSHU JAPAN

MAGNITUDE - 8.8

MEASUREMENTS OR REPORTS OF TSUNAMI WAVE ACTIVITY

GAUGE LOCATION LAT LON TIME AMPL PER

DART 21413 30.5N 152.1E 0659Z 0.76M / 2.5FT 32MIN

HANASAKI HOKKAIDO J 43.3N 145.6E 0657Z 2.79M / 9.2FT 76MIN

DART 21401 42.6N 152.6E 0643Z 0.67M / 2.2FT 40MIN

DART 21418 38.7N 148.7E 0619Z 1.08M / 3.5FT 06MIN

LAT - LATITUDE (N-NORTH, S-SOUTH)

LON - LONGITUDE (E-EAST, W-WEST)

TIME - TIME OF THE MEASUREMENT (Z IS UTC IS GREENWICH TIME)

AMPL - TSUNAMI AMPLITUDE MEASURED RELATIVE TO NORMAL SEA LEVEL.

IT IS ...NOT... CREST-TO-TROUGH WAVE HEIGHT.

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 CONFIRM THAT A TSUNAMI HAS BEEN GENERATED

WHICH COULD CAUSE WIDESPREAD DAMAGE. AUTHORITIES SHOULD TAKE

APPROPRIATE ACTION IN RESPONSE TO THIS THREAT. THIS CENTER WILL

CONTINUE TO MONITOR SEA LEVEL DATA TO DETERMINE THE EXTENT AND

SEVERITY OF THE THREAT.

A TSUNAMI IS A SERIES OF WAVES AND THE FIRST WAVE MAY NOT BE THE

LARGEST. TSUNAMI WAVE HEIGHTS CANNOT BE PREDICTED AND CAN VARY

SIGNIFICANTLY ALONG A COAST DUE TO LOCAL EFFECTS. THE TIME FROM

ONE TSUNAMI WAVE TO THE NEXT CAN BE FIVE MINUTES TO AN HOUR, AND

THE THREAT CAN CONTINUE FOR MANY HOURS AS MULTIPLE WAVES ARRIVE.

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.
