Anchorage (KTUU) — Scientists with the Alaska Volcano Observatory are keeping a close eye on Cleveland Volcano after satellite observations detected a small lava flow over an active vent, increasing the possibility of explosive activity in the coming days and weeks.
According to an AVO alert published Tuesday, satellite imagery captured Monday shows the likely presence of a circular lava flow about 80 meters in diameter on the floor of Cleveland's summit crater.
Seismic and other geophysical data is currently unavailable to observers, but AVO says that the lava flow over the active vent on the crater floor "increases the possibility of a vent clearing explosion in the coming days to weeks," according to the alert.
The last detected explosion at Cleveland Volcano was on May 4. AVO says occasional explosive activity at Cleveland may occur without warning.
