２日前にタスマニアで巨大地震


　スマトラ沖地震のあまりの甚大な被害のせいか、日本国内ではほとんど報道され
ませんが、２日前の24日午前1時59分（日本時間では23日午後10時59分）、タスマ
ニアの首都ホバートの南約800kmの沖合いで、近年では世界最大級マグニチュード
8.1の巨大地震が発生していました。
　同じプレート上のことですので、何か関連がありそうです。今後の調査や報道が
待たれます。

Massive earthquake shakes island

December 24, 2004
THE world's biggest earthquake in almost four years has struck 800km off
the coast of Tasmania, Australian seismological officials said.
Geoscience Australia said the quake, measuring 8.1 on the Richter Scale,
hit the Macquarie Rise in the Pacific Ocean at 1.59am (AEDT).

The earthquake, which occurred half-way between Australia and Antarctica,
was felt throughout Tasmania, seismologist Cvetan Sinadinovski said.
It caused buildings in parts of the state to shake for up to 15 seconds, he said.
No one was injured in the quake and structures were in no danger of
collapsing because it struck so far off the coast.
“If it happened underneath a population centre in Australia, this would
probably have destroyed a whole city,” Dr Sinadinovski said.
“In terms of size, this could have been more than 30 times stronger than
the Newcastle event of 1989.”
It was the biggest quake since one occurred off the coast of Peru in
early 2001, Dr Sinadinovski said.
He said large earthquakes were common in the Macquarie Rise region,
occurring every one or two years.
“This was an inter-plate earthquake between Indo-Australian and Pacific
plates,” he said.
”The last earthquake of similar magnitude in the Macquarie Rise region
was in 1924.
The quake originally registered as 7.8 on the Richter scale but had been
upgraded to 8.1 this morning, he said
