Four ash emissions advisories have been issued for the Karymsky since November 8, 2020 at 2:56 p.m. UTC. VAAC Anchorage mentions an ash plume at an altitude of 6,000 meters (flight alt. 200)
The ashes, partially obscured by clouds, drift northeast.
The KVERT reports moderate eruptive activity, accompanied by a 25 km by 9 km ash cloud, drifting 30 km from the volcano.
Mirova reports a small thermal anomaly on November 8 from VRP - 4-6 MW.
Last month, the GVP reported explosions on October 21, 23, and 25-26 with plumes reaching 5,000 meters, and thermal anomalies on October 23-24, 26 and 28.
The aviation code remains orange.

The National Institute of Seismology, Volcanology, Meteorology and Hydrology -INSIVUMEH- reported on the morning of Monday, November 9 that the Pacaya volcano presents a lava flow on the southwest flank with an approximate length of 800 meters.
The appearance of more lava flows on other flanks in the coming hours or days is not excluded, reported the scientific entity in its volcanological bulletin.
Weak and moderate Strombolian-type explosions are reported. Due to atmospheric conditions, it is not possible to observe the volcanic material, said the Volcanic Prevention Unit -UPV- of the Executive Secretariat of the National Coordinator for Disaster Reduction -SE-CONRED-, which maintains a constant monitoring of the Pacaya volcano.
For their part, the local coordinators for disaster prevention - COLRED - reported on Sunday 8 and in the morning of 9 November that explosions with abundant ash were observed, recorded in communities near the volcano. At the same time, the degassing would go south and south-east.

During the day from November 8 to 9, several gas and ash emissions were observed at the Reventador, reaching up to 1000 meters above the level of the crater, drifting towards a northern sector.
The VAAC Washington issued 3 alerts of emissions, detected by satellite, which reached 1,400 meters above the crater.
MIROVA recorded 1 weak thermal anomaly. The MOUNTS system did not detect any SO2 emissions exceeding the minimum daily threshold (0.1 tonnes).
When the volcano was cleared, emissions of ash, nocturnal incandescence in the crater and the rolling of the blocks on the northeast flank, descending to 600 meters below the level of the crater could be observed.
A lava flow continues to be active (~ 450m) towards the northeast and without major changes.
Seismicity is characterized by 82 LP earthquakes, 73 explosion earthquakes and discontinuous tremor.
The alert level remains naranja

In Costa Rica, at 03:55:00 local time on November 09, 2020, an eruption was recorded at the Rincon de la Vieja volcano, the height reached by the eruptive column is unknown due to the visibility conditions of the site.
Duration of activity: 1 minute.
At 3:23 p.m. local time, another eruption was recorded at Rincón de la Vieja, with a dark gray plume rising 100 meters above the height of the crater and 2016 m.a.s.l. (meters above sea level) (6,612.48 feet).
Duration of activity: 1 minute.
The seismicity of the Poás volcano continues to show signs of increasing, with frequent low frequency volcanic earthquakes, intermittent bottom tremor and small tremor of short duration.
Sub-aquatic fumaroles emit sulfur compounds which float in the lake (see photo).
No significant magmatic gas concentration is recorded.
