SYDNEY, Australia – A magnitude 6.7 earthquake rocked the coast of Australia's remote Macquarie Island Tuesday, the U.S. Geological Survey said.
The quake struck west of Macquarie Island at 2:54 p.m. local time, and was centered 6 miles below the seabed. The U.S. Geological Survey originally recorded the temblor as a 6.3 magnitude, but later upgraded the quake to 6.7.
Stuart Koyanagi, a geophysicist at the Pacific Tsunami Warning Center at Ewa Beach, Hawaii, said the quake was unlikely to generate a major Pacific-wide tsunami.

"Normally at this magnitude we don't expect any kind of destructive tsunami," he said.
The isolated, sparsely populated island lies around 835 miles south of the island state of Tasmania, and serves as a base for Australian expeditions to Antarctica.
