Reventador volcano (Ecuador): activity remains unchanged

No significant change in activity has occurred during the past weeks. The effusive-explosive eruption of the volcano continues.
The explosive activity continues from the active crater with near-constant ash emissions that reached 14,300 ft-14,900 ft (4,360 m-4,560 m) altitude and drifted into W direction.

Incandescent blocks slid down along the flanks and caused avalanches of material.
The lava flow on the northeast flank remains active.

Satellite images are limited due to dense clouds around the volcano.

Fuego volcano (Guatemala): activity remains unchanged at moderate-to-strong levels

The explosive eruption of the volcano has remained essentially unchanged at moderate to high levels. No significant change in activity has occurred since the last update.
Ongoing moderate-to-strong strombolian-to-vulcanian activity continues from the summit crater at regular intervals of 9 to 12 per hour showering the summit cone with glowing lava bombs. Incandescent material is being ejected to an approximate height of several hundred meters above the crater and caused moderate to strong avalanches of material as can be seen in the attached video.
Plume of ash rose to an estimated altitude of 4,700 ft (15,420 m) and extending about 15-20 km to the NW of the volcano.
