Report prepared by the U.S. Geological Survey.

NORTHERN MARIANAS VOLCANOES
No eruptive activity or significant unrest was detected at the Northern Mariana Island volcanoes during the past week.

Monitoring of Northern Mariana Islands Volcanoes

Northern Mariana Island volcanoes are monitored using distant seismic stations in Guam and Chichijima, Japan, hydroacoustic data from Wake Island, seismo-acoustic sensors on Saipan, and by examining satellite imagery.

This level of monitoring can detect significant volcanic activity in the CNMI but cannot provide advanced warning of eruptions.

Due to a lack of geophysical monitoring on any of the volcanic islands, all volcanoes have alert levels of UNASSIGNED. This includes Anatahan, Sarigan, Farallon de Pajaros, Supply Reef, Maug, Asuncion, Agrigan, Pagan, Almagan, and Guguan.
