Current tremor signal (ESLN station, INGV Catania)
MODIS hot spot data (past 7 days) for Klyuchevskoy volcano (ModVolc, Univ. Hawaii)
Tremor amplitude during the past 30 days (GeoNet)
Stromboli (Eolian Islands, Italy): Our friend Petra who climbed the volcano last night reports that activity is rather low at the moment. There were no explosions observed during the time spent at the summit (about one hour).
Small eruption from Popocatépetl yesterday
Etna (Sicily, Italy): The capricious Sicilian lady seems undecided what to do. The sporadic strombolian activity from the New SE crater has last been observed (to our knowledge) about 2 days ago. Temor is currently low, and generally bad weather doesn't help detailed direct observations.
Klyuchevskoy (Kamchatka): The effusive and mildly explosive eruption continues and has been gaining strength. KVERT reports increasing tremor (amplitude of 73.4 mcm/s today). Strombolian activity at the summit crater accompanies effusion of several lava flows on the north-west, west and south-western volcanic flanks.
Satellite data showed a big thermal anomaly over the volcano. Gas-steam plumes containing small amount of ash extended 150 km to the south-east of the volcano.

Batu Tara (Sunda Islands, Indonesia): An explosion yesterday ejected an ash plume rising to an estimated 7,000 ft (2.1 km) altitude, VAAC Darwin reported.
Dukono (Halmahera): Strombolian to vulcanian activity has been increasing apparently. Ash plumes reaching 7,000 ft (2.1 km) altitude have been observed again yesterday on satellite data.
White Island (New Zealand): (9 Oct) A small steam and mud eruption occurred yesterday, following the small energetic steam venting on 4 Oct and another increase in seismic activity during 7 Oct. Since then, seismic activity has decreased again.
GeoNet reports: "This afternoon (8 Oct) from about 3.05 pm until 3.20 pm there was a period of strong seismicity, which was accompanied by acoustic signals and a minor steam and mud eruption. This generated a steam plume which might have been seen from the mainland. Because these small eruptions have become more frequent the Aviation Colour Code has been raised from Green to Yellow but the Volcanic Alert Level remains at 1."

Veniaminof (Alaska Peninsula, USA): (9 Oct) The eruption of Veniaminof continues with the effusion of lava from the cone in the summit caldera.
Seismic activity remains elevated, but constant. Elevated surface temperatures consistent with the continued extrusion of lava were observed in several images during clear periods over the past day. No ash detected. (AVO daily update)
Popocatépetl (Central Mexico): The number of emissions has increased to about 2 per hour, and several smaller explosions occurred during the past days, generating ash plumes reaching up to about 1 km above the crater.
Santa María / Santiaguito (Guatemala): No significant changes occurred over the past days. INSIVUMEH's volcano observatory reported two explosions this morning with ash plumes of about 600 m height, causing light ash fall in La Florida and parts of Monte Claro. No activity was observed at the lava flows on the dome's flanks.
Pacaya (Guatemala): Relatively intense strombolian activity continues and produces a plume of fine ash and gasses. During times when the wind blows from the north, this plume can reach the capital's airport, INSIVUMEH warned two days ago.
Fuego (Guatemala): Activity has decreased again to relatively low to moderate levels. The recent increase did not result in another paroxysm.
INSIVUMEH reported few small explosions, and continuing but reduced lava effusion. This morning, the lava flow directed towards the Taniluya canyon was 300 m long.
