(11) Volcanic Activity Summary:A NOAA research vessel in the vicinity of Pagan Volcano has reported night time observations of incandescence at the summit of the volcano. Eruptive activity is considered currently to be at a low level; however with the possibility that the activity may escalate the Aviation Color Code for Pagan has been raised to YELLOW and the Volcano Alert Level to ADVISORY. Recent satellite images have been obscured by clouds.

Pagan is not monitored with ground-based geophysical instrumentation and the only source of information is satellite observation and occasional reports from observers who pass by or visit the island. We will continue to evaluate satellite imagery and on-island 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.
