Palmer: A 6.4- magnitude earthquake
followed by a series of strong aftershocks struck in a remote
area of Alaska`s Aleutian Islands, but there were no immediate
reports of injury or damage, officials said.

Geophysicist Guy Urban at the West Coast and Alaska
Tsunami Warning Centre in Palmer says that while the quakes
might have been felt in the small island community of Adak,
the centre has heard no reports of damage. No tsunami warning
was issued.

The US Geologic Survey says the first quake was
recorded at 6:26 pm yesterday and was centred in the sea
about 100 km southeast of Adak and about 1,900 km southwest of
Anchorage.

Over the next hour quakes struck with magnitudes of
6.1, 5.3 and 4.6. All were centred in the same area as the
larger quake.

Coast Guard Petty Officer Sean Terry said state
emergency officials have not reported any problems on Adak
related to the quakes.

The sparsely populated region is frequently hit by
large quakes, which often go almost unnoticed by villagers on
remote islands.

In July, a magnitude-6.7 quake struck in the area but
caused no problems. It was followed by as many as two dozen
strong aftershocks.

Two quakes measuring about 6.0-magnitude rumbled under
the Bering Sea off Alaska in May but were too far from land to
be felt.
