Magnitude 6.9 earthquake strikes Tasmania’s Macquarie Island

Australia was briefly placed on tsunami alert after a powerful earthquake struck a Tasmanian island in the southwestern Pacific Ocean.

A powerful 6.9 magnitude earthquake struck a Tasmanian island in the southern Pacific Ocean and briefly placed Australia on “tsunami watch” on Thursday.

The quake, which was revised down from an initial magnitude of 7.3 on the Richter scale, had a depth of 10 km, according to the Bureau of Meteorology and the United States Geological Survey (USGS).

It struck Macquarie Island which is located 1,600km southeast of Tasmania, about halfway between New Zealand and Antarctica.

The island is part of Australia and is governed by the state of Tasmania. Macquarie Island’s only human population are with the Australian Antarctic Division which maintains a base there.

Australia was on “tsunami watch” for around an hour before the threat was downgraded.

The US Tsunami Warning System said there was no tsunami warning after the quake.

The USGS recorded the quake at a 6.7 magnitude in a preliminary report but later confirmed it reached 6.9 on the Richter scale.

Macquarie Island became a Tasmanian State Reserve in 1978 and was inscribed as a UNESCO World Heritage Site in 1997.

It’s also home to a research station set up in the 1940s as a half way point for a radio link between Australia and Antarctica.

Between 14 and 40 people live on the island at any one time.

Earthquakes are not uncommon in the region and Macquarie Island has been hit by severe tremors in the past.

In 2004, a huge 8.1 magnitude earthquake struck off the coast and was felt as far away as Tasmania.

It was the strongest earthquake in the area since the 8.2 magnitude tremor of 1989.
