Anatahan eruptions continue

Volcanic explosions every few minutes continued on Anatahan yesterday, but in varying magnitudes.
The Emergency Management Office and the U.S. Geological Survey said, though, that the peak of the eruption was nearly half the magnitude of last February’s volcanic eruption.
“Occasional small explosions occurred every few minutes to tens of minutes, undoubtedly associated with cinder cone formation,” the agencies said.
The agencies maintained that steam and ash extended to at least 200 kilometers, while volcanic smog reached about 200 kilometers farther in the westerly and west-northwest directions.
Anatahan’s rumbling volcano spewed ash that reached an altitude of about 19,000 feet over the weekend. The volcanic activity appeared to be intensifying, although the island has been recording fluctuating seismicities.
The volcano has been erupting for the third time this year since March 18, spewing clouds of ash into the air days after a scientific mission collected from Anatahan volcanic rock samples and measured emissions of sulfur dioxide, a major air pollutant.
