Earthquake swarm related around Manu’s islands continues to decrease


The earthquake swarm related to Taʻū Island has continued at decreased rates over the past two weeks.

The position of the earthquake source has not changed. Beginning today the Hawaiian Volcano Observatory will issue weekly updates for Taʻū Island instead of daily updates. Additional messages will be issued if needed. 

This is according to the US Geological Survey.

No felt earthquakes were reported over the past 24 hours. The satellite data from the previous 24 hours observed no volcanic activity. 

The National Earthquake Information Center (NEIC) will soon start publishing preliminary locations of the largest earthquakes that have occurred during this period of seismic unrest in American Samoa. These locations will appear 

However, in the Manuʻa Islands, the earthquake locations and depths are currently best-estimates, with large uncertainties resulting from the monitoring network being constrained to the east-west orientation of the islands in American Samoa.
