(11) Volcanic Activity Summary:Clear to partly cloudy satellite images showed a persistent gas and steam plume extending from Pagan Volcano throughout the past week. The plume was similar in character to those observed the previous week. USGS has received no other reports of unrest or activity at the volcano this week.

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 has been detected at other volcanoes in Northern Mariana Islands this week.
