The eruption continues on the northern crater of the Cerberus volcano on Semisopochny Island, the Alaska Volcano Observatory said.

Seismicity at the volcano remains elevated and variable, with periods of continuous tremors and periodic short-term explosions lasting several minutes.

These explosive events produce small ash clouds that typically rise 3 to 4.6 km (10,000 to 15,000 feet) above sea level and dissipate within an hour or two (according to satellite observations).

Periods of ash ejection at lower altitudes, interspersed with strong soaring, were observed in webcam images on September 7.

These ash clouds were blown horizontally with slight vertical lift at less than 1.5 km (5,000 ft) above sea level.

Sulfur dioxide emissions continue to be observed in satellite data (once a day).

Small eruptions with light ash deposits in the vicinity of the active northern crater of the Cerberus volcano and ash clouds, usually less than 3 km (10,000 feet) above sea level, characterize recent activity that shows no signs of abating, the observatory added.

Small explosions can continue and be difficult to detect, especially in poor weather conditions.

The Semisopochny Island is monitored using local seismic and infrasound sensors, satellite data, web cameras, as well as remote infrasonic and thunderstorm networks.
