USGS Volcano Hazards Program Volcano Update
NMI update page and observatory web site
A minor, low altitude ash cloud from Pagan Volcano was reported by the Washington VAAC on Tuesday July 10. AVO reviews of satellite data confirmed the cloud. Local observations indicated localized ash fall on or near the Island. Minor steam and gas plumes were observed in satellite images throughout the past week. The USGS received no further reports of unrest or activity at Pagan volcano.
Pagan Volcano is not monitored with ground-based geophysical instrumentation and the only sources of information are satellite observations and occasional reports from observers who pass by or visit the island. We will continue to evaluate satellite imagery, on-island, and mariner reports when they become available, but because the volcano is not monitored with ground-based instruments, we cannot provide advanced warning of activity.
Access to the island may be restricted by the CNMI government. Contact the EMO for the latest information.
No eruptive activity or significant unrest was detected at other volcanoes in Northern Mariana Islands this week.
