USGS reports 6.6 magnitude quake Southwest of Samoa’s capital, no tsunami warning issued

A magnitude-6.6 earthquake struck near the island nation of Samoa on Friday, July 25, the US Geological Survey (USGS) reported. The quake occurred 440 kilometers (273 miles) southwest of Samoa’s capital, Apia, at a depth of 314 kilometers (195 miles).

There were no immediate reports of injuries or structural damage. A staff member at the Samoa Observer news website told AP they had not felt the earthquake and had not received any reports of damage.

The US Tsunami Warning System confirmed no tsunami warning was issued following the quake.


Samoa lies on the "Ring of Fire," a seismically active region that circles the Pacific Ocean. Earthquakes and volcanic activity are common in this zone.

In 2009, two powerful earthquakes between Samoa and American Samoa triggered tsunamis that killed at least 192 people across Samoa, American Samoa, and Tonga.

About USGS

The US Geological Survey (USGS) is a scientific agency of the United States government responsible for studying the natural landscape, natural resources, and natural hazards of the country. It operates under the US Department of the Interior and plays a key role in monitoring earthquakes, volcanoes, landslides, and other geologic events around the world.

The agency uses a network of sensors, satellites, and research stations to collect data and provide real-time information to the public and decision-makers.

When it comes to earthquakes, the USGS maintains the National Earthquake Information Center (NEIC), which tracks seismic activity globally.

It issues immediate reports on earthquake location, depth, and magnitude to inform emergency response and public safety. The agency also collaborates with international and regional partners to improve global earthquake monitoring and hazard assessment.
