EVALUATION
A SIGNIFICANT TSUNAMI WAS GENERATED BY THIS EARTHQUAKE.
HOWEVER...SEA LEVEL READINGS NOW INDICATE THAT THE THREAT HAS
DIMINISHED OR IS OVER FOR MOST AREAS. THEREFORE THE TSUNAMI
WATCH ISSUED BY THIS CENTER IS NOW CANCELLED.

LEAST TWO HOURS AFTER THE ESTIMATED ARRIVAL TIME 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.
THIS WILL BE THE FINAL BULLETIN ISSUED BY THE PACIFIC TSUNAMI

TSUNAMI WARNING CANCELLED
TSUNAMI WATCH LIFTED AFTER TWO BIG EARTHQUAKES
Jakarta, Indonesia (CNN) -- A massive earthquake struck off the coast of the Indonesian island of Sumatra Wednesday afternoon, triggering a tsunami watch for the Indian Ocean, which was later canceled.
The quake struck about 434 kilometers (270 miles) southwest of Banda Aceh, the capital of Indonesia's Aceh province, and had a magnitude of 8.6, the U.S. Geological Survey said. It took place at a depth of 23 kilometers (14 miles).
A second large quake, with a magnitude of 8.2, occurred off the west coast of Sumatra about two hours later, the USGS said.
Gary Gibson from the Seismology Research Center in Melbourne, Australia, said the location of the second quake reduces the possibility of a tsunami.
There was also a series of smaller quakes off the west coast of northern Sumatra with magnitudes between 5.1 and 5.4.
There were no immediate reports of destruction or deaths Wednesday.
Indonesian President Susilo Bambang Yudhoyono said on local television that there were no reports of casualties or damage in Aceh.
The Pacific Tsunami Warning Center issued a tsunami watch for the entire Indian Ocean.
A few hours later, the center announced the tsunami watch was canceled.
"A significant tsunami was generated by this earthquake. However, sea level readings now indicate that the threat has diminished or is over for most areas," the center said.
DR. KIJAZI, THE DIRECTOR OF METROLOGICAL AGENCY IN TANZANIA: COAST OF DAR ES SALAAM WILL BE HIT BY TSUNAMI WAVES
Dr. Kijazi, the Director of Metrological Agency in Tanzania, said today that the coast of Dar es Salaam will be hit by tsunami waves. According to her, the incident is expected to happen at the Dar es Salaam coast strip between 1900 hours EAT and 2100 hours EAT. She was interviewed via telephone by TBC.
