Indonesia hit by magnitude 7.0 earthquake
A MAGNITUDE 7.0 earthquake has hit off the coast of Abepura in Indonesia, the US Geological Survey site has reported.
But warning centres say the quake was not significant enough to cause a tsunami threat.
The underwater quake hit 234km from the city of Abepura.
The Australia-Pacific plate boundary is over 4000 km long on the northern margin, from the Sunda (Java) trench in the west to the Solomon Islands in the east, the site explains.
The eastern section is over 2300 km long, extending west from northeast of the Australian continent and the Coral Sea until it intersects the east coast of Papua New Guinea.
The boundary is dominated by the general northward subduction of the Australia plate.
"On April 1, 2007, a M8.1 interplate megathrust earthquake occurred at the western end of the trench, generating a tsunami and killing at least 40 people.
"This was the third M8.1 megathrust event associated with this subduction zone in the past century; the other two occurred in 1939 and 1977,'' the site reports.
