Japan quake: Pacific tsunami warning

A massive 8.9 quake and huge tsunami have struck northern Japan, triggering a wider tsunami alert around the Pacific rim.

2036: A contact in the Philippines reports that 19 provinces in north Luzon are on high alert. Tsunami waves have already reached the vicinity and more waves are expected to hit. No reports of casualties.

With a dam reportedly having broken in Fukushima prejecture, washing away homes, and Japanese authorities monitoring the nuclear plants, one question arise: Do we still want to go ahead with a 100-storey tower, nuclear power plants and more dams of our own in Malaysia?

A tsunami warning is in effect for Japan, Russia Taiwan, Yap, Philippines, Marshall Is., Belau, Midway Is., Pohnpei, Chuuk, Kosrae, Indonesia, Papua New Guinea, Nauru, Johnston Is., Solomon Is., Kiribati, Howland-baker, Hawaii, Tuvalu, Palmyra Is., Vanuatu, Tokelau, Jarvis Is., Wallis-futuna, Samoa, American Samoa, Cook Islands, Niue, Fiji, New Caledonia, Tonga, Mexico, Kermadec is, Fr. Polynesia, Pitcairn, Guatemala, El Salvador, Costa Rica, Nicaragua, Antarctica, Panama, Honduras, Chile, Ecuador, Colombia, Peru.

1730: A contact in the Philippines says they are on a Level 2 alert there and the critical watch-out period is between now and 7.00pm (Malaysian/Philippines time).

The tsunami is also expected to reach Hawaii at just after 3.00am (Hawaii time)/9.00pm (Malaysian time)

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.
BULLETINS WILL BE ISSUED HOURLY OR SOONER IF CONDITIONS WARRANT.
THE TSUNAMI WARNING WILL REMAIN IN EFFECT UNTIL FURTHER NOTICE.
THE JAPAN METEOROLOGICAL AGENCY MAY ALSO ISSUE TSUNAMI MESSAGES
FOR THIS EVENT TO COUNTRIES IN THE NORTHWEST PACIFIC AND SOUTH
CHINA SEA REGION. IN CASE OF CONFLICTING INFORMATION… THE
MORE CONSERVATIVE INFORMATION SHOULD BE USED FOR SAFETY.
THE WEST COAST/ALASKA TSUNAMI WARNING CENTER WILL ISSUE PRODUCTS
FOR ALASKA…BRITISH COLUMBIA…WASHINGTON…OREGON…CALIFORNIA.
