Anatahan volcano began erupting in 2003 and continued with a second eruptive phase in 2004. In January 2005 the volcano began a sequence of eruptions and unrest that continues as of September 2005. The activity has been characterized by punctuated episodes of very steamy strombolian activity and vigorous ash emission. Some of the ash emissions have reached 50,000-foot elevations, with VOG and ash occasionally reaching the Philippines and southernmost Japan, over 1000 miles away. Vigorous ash emission has been almost continuous since June 2005. A M4.8 long-period earthquake (LP) occurred in mid-August, one of the largest LPs recorded on the planet in the last quarter-century. Real-time monitoring consisting of a few telemetered short-period seismometers and acoustic sensors has been severely hampered by ashfall on the small island. Monitoring efforts have been focused on the aircraft/ash hazard, with the goal of providing the FAA and airline industry with rapid notice of seismic signatures that may indicate ash columns rising to the altitude of airline traffic, or nominally above 20,000-30,000 ft.
