Vanuatu hit by aftershocks following big quake

8:57 pm on 11 August 2010

A strong 6 magnitude quake has shaken Vanuatu, a day after a bigger tremor triggered a small tsunami and sent people fleeing the coast.

The US Geological Survey says the tremor hit mid afternoon at a depth of 41 kilometres, 75 kilometres west-northwest of Port Vila.

Tuesday's earthquake, located about 35 kilometres northwest of VIla at a depth opf shook buildings in the city for about 15 seconds.

It didn't appear to have caused significant damage, but the resulting minor tsunami triggered panic.

Seismologists at Geoscience Australia says the latest quake is to be expected in the wake of such a large earthquake.

Since the start of July, at least three earthquakes measuring 6.0 or above have hit Vanuatu, while a 7 point 2 tremor prompted a brief tsunami alert.
