The earthquake swarm related to Taʻū Island continues with no significant change in the past 24 hours.
Data shows the earthquake swarm is occurring in a fixed position, but the precise location has been difficult to resolve.
This is according to the US Geological Survey’s latest statement issued yesterday.
“Preliminary estimates include a narrow band of possible locations from approximately 30 km (19 mi) beneath the central northern coast of Taʻū Island to an area about 5 km (3 mi) beneath the ocean surface 20 km (13 mi) north of Taʻū Island. Seismologists continue to examine data and refine locations.
“In the past 24 hours, the USGS seismic network detected 21 earthquakes that were large enough to be felt by people on the Manuʻa Islands.
The largest event of September 2 was a magnitude 3.4. Many small earthquakes undetectable by humans also continue.
The American Samoa Emergency Operations Center continues to receive reports of felt earthquakes and booming sounds.
No volcanic activity was observed in available satellite data from the previous 24 hours.”
