Volcano: Pagan (CAVW #0804-17=)

Current Volcano Alert Level: ADVISORY

Current Aviation Color Code: YELLOW

Issued: Friday, May 10, 2013, 7:16 AM ChST (20130509/2116Z)
Source: U.S. Geological Survey
Notice Number: 2013/N1

Elevation: 1870 ft (570 m)
Area: Mariana Islands

Volcanic Activity Summary: A gas and water vapor plume from Pagan was visible in satellite images over 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.

No eruptive activity or significant unrest was detected at other volcanoes in Northern Mariana Islands this week.
