The Earth is still ringing like a bell about two weeks after the earthquake that shook the Indian Ocean and triggered the tsunamis in Asia, according to Australian scientists here.

Australian Broadcasting Corporation on Sunday quoted Herb McQueen from the Australian National University as saying that a gravity meter is still detecting ringing from the rare seismic event.

He said the data is being studied by scientists across the world.

"Normally a reasonably large earthquake will continue reverberating for a couple of days on our charts, but this one has been going steadily for the last 12 to 13 days and shows no signs of letting up actually," he said.

"There's still a measurable oscillation," and "I've never seen the earth ringing this long after an earthquake," he said.
