Pavlov (Alaska Peninsula, USA): No further activity has been detected during the past days. Alert status is at yellow.

Popocatépetl (Central Mexico): Activity has been reduced during the past days. Occasional explosions produced steam and ash plumes rising about 1 km above the crater and the frequency of small emissions has been about 3 per hour.
Most of the time, the summit of the volcano has been in clouds, but occasionally, a weak steam and ash plume, as well incandescence at night could be observed. CENAPRED maintains alert level "Yellow Phase 3".

Santa María / Santiaguito (Guatemala): A lahar descended the valley of the Nimá I river at 13:30 h local time yesterday, caused by heavy rainfalls mobilizing pyroclastic deposits. The mud flow was about 30 m wide, dense, hot and stinking of sulfur, and carried large boulders (up to 3 m across).

Pacaya (Guatemala): Activity has decreased and strombolian activity has dropped or even stopped for the time being. INSIVUMEH reported only degassing sounds for yesterday.

Fuego (Guatemala): Activity remains weak, but due to heavy rainfall, INSIVUMEH warns of lahars through the drainages of the Ceniza, Las Lajas and El Jute canyons, as well the valleys Taniluyá and Santa Teresa.

Copahue (Chile/Argentina): The alert level of the volcano was lowered from "red" to "orange" in response to a declining trend of seismic activity recorded under the volcano. However, seismic activity remains significant and monitoring efforts continue at maximum level.
The Civil Defence (ONEMI) allowed the 621 evacuees from the Chilean side to return to their homes, while another about 600 evacuees from the Argentina side still remain in evacuation centers.
