ANATAHAN VOLCANO (CAVW#0804-20=)
16.35°N 145.67°E, Summit Elevation 2592 ft (790 m)
Volcano Alert Level: ADVISORY
Aviation Color Code: YELLOW
Report prepared by the U.S. Geological Survey.
The Aviation color code is being lowered from Orange to Yellow and the Alert level from Watch to Advisory at Anatahan volcano. Seismicity remains low. Photographs from a visit to the volcano Aug. 8 show a low-level (6,000-7,000 ft above sea level) relatively passive steam plume rising above the island. Occasional SO2 plumes have been seen over the past few weeks by satellite, but no ash has been identified.
During times of northerly winds, the Anatahan plume, if present, could be directed towards the CNMI and Guam. If this happens, residents may notice hazy air conditions and smell sulfur. The Emergency Management Office (EMO) of the CNMI government will issue volcanic haze and sulfur advisories if appropriate.
Access to the island may be restricted by the CNMI government. Contact the EMO to get the latest information.
