SINABANG, Indonesia, April 7 (Reuters) - A major earthquake
of 7.7 magnitude struck off the coast of Aceh on the Indonesian
island of Sumatra on Wednesday, but there were noimmediate
reports of casualties.
A Reuters photographer in Sinabang on Simeulue island, south
of Aceh, said there was panic and electricity was cut off after
the quake. Metro TV reported that people rushed to higher ground
in some areas.
Aceh Governor Irwandi Yusuf said there had not been reports
of damage or casualties so far.
"I am on the coast now, some people had gone to take refuge
on higher ground but now they have returned to their homes,"
Yusuf told Metro TV.
The quake, which struck around 5:15 a.m. (2215 GMT), was
centred 200 km (125 miles) west-northwest of the coastal town of
Sibolga and was at a depth of 31 km, the U.S. Geological Survey
said. The epicentre was around 215 km from Medan, the largest
city o Sumatra.
The Reuters witness said there were at least three
aftershocks.
The Hawaii-based Pacific Tsunami Warning Center initially
warned the quake could generate a local tsunami, but later
cancelled its tsunami watch, saying: "Sea levelreadings indicate
that a significant tsunami was not generated."
An official from Indonesia''s meteorology agency said a tiny
tsunami of only 3 cm (1 inch) had been detected at Sinabang and
lifted its own tsunami warning.
A Metro TV reporterin the Sibolga area of North Sumatra said
that he fell off his motorbike when the quake struck and the
force left electricity poles swaying for minutes afterwards.
In December 2004, a magnitude 9.15 quake off the coast of
Sumatra''s Aceh provincetriggered an Indian Ocean tsunami that
killed about 226,000 people in Indonesia, Sri Lanka, India,
Thailand and nine other countries.
