Tsunami Warning After Earthquake
Breaking News6:15pm UK, Wednesday February 11, 2009

Indonesia has issued a tsunami warning after an earthquake measuring 7.5 on the Richter scale.

The quake struck in the country's Taulad Islands, the US Geographical Survey said.

There is no threat of a widespread destructive tsunami, according to the US Pacific Tsunami Warning Centre.

But it added that earthquakes of this size sometimes generate local tsunamis which can be destructive along coasts within 100km of the epicentre.

I think they lucked out with the location of this one. Some damage but no casualties reported so far.

Quake near Indonesia's Sulawesi damages buildings
Wed Feb 11, 2009 7:37pm EST

JAKARTA (Reuters) - A powerful earthquake which struck near the Talaud Islands north of Indonesia's Sulawesi island has damaged many buildings in the area, the meteorology agency said on Thursday.

The quake, at a shallow depth of about 10 km (6.2 miles), was felt strongly in the Talaud Islands, and followed by several aftershocks. A tsunami warning issued by the agency was later lifted.

Oktifar Tribandono, an official at the agency, said many houses in the area collapsed, and two churches were damaged, but so far there have been no reports of casualties. The area lies in an agricultural belt and is sparsely populated.

The U.S. Geographical Survey initially put the quake at a magnitude of 7.5 magnitude, although later lowered its estimate to 7.0.

A reporter for Indonesia's state radio station in the town of Tahuna said frightened people had rushed out of their homes after the strong quake on the islands bordering the Celebes Sea.

The U.S. agency said the epicenter of the quake was in the Talaud Islands, 323.5 km (201 miles) south-southeast of General Santos, on the Philippine island of Mindanao. It put the quake at a depth of 33 km (20 miles).

The Indonesian archipelago suffers frequent earthquakes, lying in an area of intense seismic activity where several tectonic plates collide.

A huge Indian Ocean tsunami in 2004 killed about 230,000 people across Asia, many of them in Indonesia.

Afflicted areas are still struggling to recover and Indonesia's government has taken measures to improve readiness for such disasters.



They had quite a few strong foreshocks in the 48 hours before the event as well as some strong aftershocks in the 6 hours since.

A STRONG 6.3-magnitude aftershock struck off the northeast tip of Indonesia's Sulawesi island early today, the US Geological Survey said.

The tremor, which followed an earlier 7.0-magnitude quake, struck at 9.14am (AEDT) at a depth of 35 kilometres, the US agency said.

There were no immediate reports of any casualties or damage.

Earlier today, a tsunami warning was issued after the 7.0-magnitude earthquake struck off the northeast tip of Sulawesi island.

The warning was retracted about one hour after the quake hit, according to Indonesia's meteorology and geophysics agency website.
