The explosive eruption of the volcano continues characterized by low-level ash emissions from the Mount Cerberus crater.
Plumes of ash continue to rise to an altitude of 10,000 ft (3,048 m), but the intensity over the past four weeks is higher-than-usual as the ash columns are being sent to an altitude of 13,000 ft (4,000 m). A volcanic ash is spreading about 300 km of the volcano.

Interaction of groundwater and magma produces fine-grained ash as it rises within the volcano edifice. In addition, satellite-based measurements of sulfur dioxide (SO2) concentrations in the atmosphere show confirm a new batch of magma inside the volcano's conduits.
The alert level for the volcano remains at "orange".


Fuego (Guatemala): Mild explosive activity continues from the volcano. The Volcanic Ash Advisory Center (VAAC) Washington reported intermittent emissions of volcanic ash plumes.
The full report is as follows: sporadic emissions of volcanic ash

Telica (Nicaragua): (2 Sep) A continuing dense and strong ash emissions occurred from the active vent today starting around 06:40 local time.
