Volcano Watch — USGS Hawaiian Volcano Observatory monitors American Samoa
In July 2022, earthquakes at Taʻū volcano shook the remote Manuʻa Islands of American Samoa for 6 weeks as the volcano experienced volcanic unrest; fortunately for the communities of Taʻū Island and nearby Ofu-Olosega Islands (also a volcano), seismic unrest subsided and returned to background levels of activity in September 2022.

Earthquakes have been felt since late July in the Manuʻa Islands of American Samoa in the South Pacific. These earthquakes are likely associated with magmatic activity beneath the islands.

“If activity escalates to an eruption, it will most likely include slow-moving lava flows or low-level explosions of lava that are localized to a small area. An eruption like Hunga Tonga–Hunga Ha’apai in Tonga earlier this year is extremely unlikely as it is a different type of volcano. Volcanoes in Tonga erupt much more explosively than ones in American Samoa and Hawaiʻi,” according to the Hawaiian Volcano Observatory.
