NORTHERN MARIANA ISLANDS WEEKLY UPDATE
Friday, February 22, 2013 11:01 AM ChST (Friday, February 22, 2013 01:01 UTC)


Report prepared by the U.S. Geological Survey.

PAGAN VOLCANO (CAVW #0804-17=)
18°7'48" N 145°48' E, Summit Elevation 1870 ft (570 m)
Current Volcano Alert Level: ADVISORY
Current Aviation Color Code: YELLOW

A gas and water vapor plume downwind from Pagan was visible in satellite images every day during the past week. This is typical of recent months of observation of Pagan.

Because of this ongoing emission of volcanic gas from Pagan, it remains possible that residents of the CNMI may notice sulfurous odors under certain wind conditions. Additional information about volcanic gas and vog can be found online at this address: http://hvo.wr.usgs.gov/hazards/FAQ_SO2-Vog-Ash/main.html

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.
