Kliuchevskoi (Kamchatka): Mild strombolian activity continues at the summit crater, producing small ash plumes that drift one after the other from the volcano. A short lava flow might still be active on the southeast side, but this is not certain from available imagery.
The alert level remains aviation orange.
Shiveluch (Kamchatka): A moderately large explosion occurred this morning (evening in Kamchatka) at the volcano, producing a plume reaching approx. 6 km altitude. Continued ash emissions followed the explosions for several hours.
Aso (Kyushu): Strombolian activity with abundant ash emissions continue with little variations from the Nakadake crater.
Soputan (North Sulawesi, Indonesia): An eruption occurred today, producing an ash plume rising to 5-6 km altitude. Darwin VAAC raised the alert level to red.
The event took place shortly after 11:30 am (local time) and was observed by from the volcano observatory. It had been preceded by a significant increase in seismicity during the past days since Wednesday. According to the local report, a rock avalanche (but apparently no pyroclastic flow) traveled down the western side of the dome, reaching a length of approx. 500 m.
Colima (Western Mexico): Frequent small to moderate explosions occur at the volcano’s summit lava dome. Thanks to the new webcam from webcamsdemexico.com, this activity can now be followed more closely.
Karymsky (Kamchatka): A small volcanic ash plume was reported this morning extending ESE from the volcano. Karymsky has intermittent strombolian to vulcanian explosions.
Zhupanovsky (Kamchatka, Russia): Intermittent ash emissions continue from the volcano. This morning Tokyo VAAC reported a small plume at flight level 120 (12,000 ft / 3.6 km altitude) extending SE.
Dukono (Halmahera): A moderately strong ash emission, possibly due to increased explosive activity, was reported this morning, reaching 9,000 ft / 2.7 km altitude. (Darwin VAAC)
Cerro Negro de Mayasquer (Colombia): Seismic activity remains high with an average of almost 1200 small quakes detected on a daily basis under the Chiles volcano.
However, it has been decreasing overall compared to last year and no events were large enough to be felt recently.
Sangay (Ecuador): A hot spot was detected in satellite data (Washington VAAC), suggesting that some mild activity continues in the summit crater of this remote volcano, one of South America’s most active.
