The waves at Pago Pago were 5.1 feet (1.57 metres) above normal sea level, according to the Pacific Western Tsunami Warning Center in Hawaii.

American Samoa is a tiny US territory that lies about halfway between Hawaii and New Zealand. It is home to about 65,000 people.

The epicenter of the quake was located 120 miles (190 km) southwest of American Samoa, a remote Pacific island, the US Geological Survey. The USGS earlier said the quake measured 7.9 magnitude. It struck at a depth of 11.2 miles (18 km).

Hawaii was monitoring the situation.

"Sea level readings indicate a tsunami was generated. It may have been destructive along coasts near the earthquake epicenter and could also be a threat to more distant coasts," the Pacific warning center said.

  1. Strange, there is a typhoon here, an earthquake there, and now there is a tsunami. They all seem to happen at the same time?!

    It has been so small I'm fearing that after a few more tsunami, those islands will sink... will they?

    and such quake is so strong... and why do quakes and tsunami happen at the same time, even in economics (after a quake on closure of Lehman Brothers, there is the 'tsunami')?

  2. gd question~
    quakes and tsunamis are closely related as long as the shaking of ocean floor trigger the displacement of water and thus generating huge waves attacking the coastal locations.
