Second Quake As Major Tremor Hits Pacific

Second Quake As Major Tremor Hits Pacific

An earthquake of 6.8 magnitude has struck off Samoa in the Pacific Ocean just hours after a major tremor rattled nearby Papua New Guinea.

The epicentre of the second quake was 77 miles (124km) west-southwest of the capital Apia, at a depth of 72.2 miles.

Earlier, vast swathes of the Pacific were put on high alert for "hazardous" tsunami waves after a powerful earthquake in Papua New Guinea.

The United States Geological Service measured it as magnitude 7.5.

The Pacific Tsunami Warning Centre warned that waves measuring up to 10ft (3m) could hit Papua New Guinea and even reach parts of Russia.

It said areas located within 620 miles (1,000km) of the epicentre of the quake were most at risk.

Coasts as far away as China, Japan, Australia, New Zealand, the Philippines, Indonesia, Hawaii, Mexico, Guatemala, Costa Rica, Panama, Colombia, Ecuador, Peru, Chile and Antarctica may also be affected, it said.

However, the Japan Meteorological Agency said the earthquake posed no tsunami risk to Japan.

The warning centre also said that the second quake posed no threat to Hawaii and a "destructive Pacific-wide tsunami" was not expected.

According to the US Geological Survey, the first quake hit at a depth of 65km, some 54km southeast of the town of Kokopo on New Britain island and 789km from the capital Port Moresby.

It was followed by multiple smaller aftershocks measuring between 4.7 and 5.7 in the same area.

Acting director of the Papua New Guinea National Disaster Office, Martin Mose, told Radio New Zealand International they had not received any reports of damage.

He said a small wave, possibly about half a metre high, did occur at Rabaul - one of the closest towns to the epicentre - but it is not thought to have affected any communities.

The Pacific Tsunami Warning Center lifted its warning at around 3.30am UK time saying the threat had mostly passed.

Earthquakes are common in Papua New Guinea which lies on the so-called Pacific Ring of Fire, a hotspot for seismic activity caused by friction between tectonic plates.
