Eruption news from Cleveland volcano:

Cleveland volcano (Aleutian Islands, Alaska): new lava dome growing in summit crater

Monday Oct 02, 2017 22:54 PM | DOOR: T

Thermal signal from Cleveland showing a moderate anomaly during the past days (Mirova)

A new lava dome is growing in the summit crater of the volcano. According to the Alaska Volcano Observatory (AVO) the new phase of lava effusion probably began on 30 September and is continuing at slow rate.
As of yesterday, the surface of the dome was around 4,200 square meters. A moderate thermal heat source can be detected on satellite data as well.

from the AVO report
"Lava effusion is typically confined to the summit crater at Cleveland, with the last significant lava flow (that extended to the ocean) occurring in 2001. The lava domes that have been erupted since 2001 have all been destroyed by explosive activity within weeks to months after lava effusion.
These explosions typically produce relatively small volcanic ash clouds that dissipate within hours, however more significant ash emissions are possible. There is no way to predict how long this lava dome will grow, or when it might be destroyed by an explosion. No significant activity related to lava effusion observed in seismic data (from the limited network on Cleveland) and no explosive activity detected in infrasound data over the past day." (AVO)
