"The quake activity indicates the volcano is relatively quiet for now and it does not appear to be building toward stronger eruptive activity," geologist Steve Brantley of the Alaska Volcano Observatory said Wednesday.
The area was established in 1918 by President Woodrow Wilson, who set aside an initial 1,700 square miles to preserve an area of "importance to the study of volcanism." Scientists want to pinpoint the size, shape and location of the eruptive vent.
Before the 1980s, the last eruptive period was from 1800 to 1857, with intermittent periods of quiet lasting months or years, according to the USGS western region office in Menlo Park, Calif.
