Low-level unrest continued at Pagan Volcano throughout the past week. Seismic activity remains above background. A vapor plume was visible in some satellite images during clear views this week. This level of unrest is typical of the past several months. An AVO field crew arrived on the island on April 3 to retrieve campaign instruments deployed last year, and to service other geophysical equipment.
Volcanic gas from Pagan may be noticed downwind of the volcano as distinctive sulfurous odors. Additional information about volcanic gas and vog can be found on the web at this address: http://hvo.wr.usgs.gov/hazards/FAQ_SO2-Vog-Ash/main.html
Access to the island may be restricted by the CNMI government. Contact the EMO for the latest information.
