New Zealand Earthquake
23 November 2004
A large earthquake occurred this morning off the west coast of the South Island, New Zealand.
The earthquake of magnitude 7.3 occurred at 9.26 am New Zealand time (7.26 am EST)
The event occurred 250 km west of Invercargill, New Zealand, at a depth of 33 km.
"The event would have been felt across the South Island," said Geoscience Australia's duty seismologist Dr Trevor Allen. "However there is unlikely to be any damage as the epicentre was located offshore," Dr Allen said.
"On average this region of New Zealand experiences an earthquake of this magnitude every 25 years. The last large earthquake was of magnitude 7.1 and occurred in August 2003," Dr Allen said.
