Sunday tremor registers 4.3 on Richter Scale

An earthquake that registered 4.3 on the Richter Scale shook homes on Sunday afternoon but it did not generate a tsunami.

This according to the Samoa Meteorological Service who published a “Felt Earthquake Bulletin” on Sunday.

According to the bulletin, posted on the weather office’s Facebook page, the tremor struck at 4.18 p.m.

It occurred at a reported distance of 259 kilometers southwest of Apia, Samoa.

Its depth was measured at 10 kilometers.

“There was no tsunami generated by this earthquake,” the bulletin said.


The Sunday quake was the second to occur in the Samoa region in less than one month.

In early September an earthquake with a 5.2 magnitude rattled homes across the country.

Its depth also measured 10 kilometers. Its distance was 184 kilometers southwest of Apia.

Two additional earthquakes were felt in Samoa in recent weeks but they occurred in the Tonga region. 

The latest Tongan quake occurred on 1 October at 3:13 p.m. and it registered 6.1 on the Richter Scale, according to the weather office.

It had a depth of 10 kilometers and its distance was 641 kilometers southwest of Apia.

A tremor on 15 September was felt in Samoa. It struck at 8:53 a.m. in the Tonga region with a depth of 10 kilometers. Its distance was 204 kilometers southwest of Apia.

There were 29 earthquakes felt in Samoa within the same time period.

None of the earthquakes that occurred in the last four weeks triggered a tsunami.

The Samoan islands are located within the Pacific Ring of Fire, where tectonic plates in the earth’s lithosphere meet and seismic and volcanic activity are triggered and become frequent.
