Strong quake hits Indonesia

From correspondents in Washington DC

November 20, 2005

A MAGNITUDE 6.5 earthquake has hit Simeulue, Indonesia, the US Geological Survey says.

"A strong earthquake occurred at 1410 GMT (1:10 AEDT) on Saturday, November 19," the USGS said on its website.

"The magnitude 6.5 event has been located in Simeulue, Indonesia," (1440km) north-west of Jakarta.

Simeulue is near the Aceh region devastated by the Indian Ocean tsunami last year.

The Pacific Tsunami Warning Centre in Hawaii said it had no information on the quake because it has no monitors outside the Pacific region.

The centre said, however, that earthquakes of such a size had the potential to create a tsunami.

Isnt that only like 1% as strong as the earthquake that caused the Tsunami recently?

That's not strong - there was a 6.2 there last week.

Slow news day in washington......

I read that it takes a Richter of 7.5 or higher to cause a tsunami and not all earthquakes of that size will produce one, its just that the conditions have to be right

Actually, there are a number of factors that can lead to an earthquake producing a tsunami. Obviously, the magnitude of the earthquake has to be taken into account, but the location of the epicenter and they type of movement are also very important. Land movement on Earthquake faults can be vertical or horizontal or a combination of the two. If the movement is largely horizontal, there will be little displacement of water and no tsunami. However, if the movement is mostly vertical, as it was last Dec. 26, a lot of water will be moved, resulting in a tsunami.

The depth of the epicenter is also an important factor. A very shallow - say 10km deep - earthquake could cause much more damage than one that is located 50km deep. Finally, there is the direction of wave propagation (sp?) and topography to be taken into account. Last December's tsunami created waves that moved more to the east and west, than to the north and south. Consequently, there was lots of damage and many casualties in Indonesia and Sri Lanka-southern India, but relatively little damage to the north in Burma or Bangladesh.
