Monte Albano (Italy): A second (and much more violent) geyser-like fumarole or mudvolcano recently appeared off shore near Fumiciono, approx. 100 meters out from the beach in the area where the new port of Rome is being built. It is an underwater vent that produces fountains of upwelling sediment-rich water driven by strong degassing from the sea floor:

Gorely (Southern Kamchatka): KVERT has no seismic data due to technical problems. The volcano continues to produce strong degassing, but has not erupted.

Klyuchevskoy (Kamchatka): Activity remains strong. A small explosion this morning produced an ash plume rising about 700 m above the summit and drifting 50 km to the east. The lava flow remains active and can be seen on webcam images at night.

Kizimen (Kamchatka): Activity (extrusion of lava at the summit) continues, but has decreased recently, as incandescent rockfalls have become more rare. Seismic activity remains "moderate" (KVERT) and strong degassing can be seen. About a week ago, the prominent spine at the summit dome collapsed.

Karymsky (Kamchatka): KVERT reported an explosion that produced an ash plume rising to 5-6,000 ft (1.5-1.7 km) altitude and drifted 30 km ESE. Seismic activity is moderate and a thermal hot spot at the summit is visible on satellite data.

Shiveluch (Kamchatka): Activity continues at moderate levels with little changes. The viscous lava dome remains active and produces occasional small ash explosions and avalanches.

Tolbachik (Kamchatka): No seismic or surface eruptive activity has been recorded recently. The eruption can probably by now be regarded to be over, but KVERT maintains Aviation Color Code yellow.

Bezymianny (Central Kamchatka Depression): The strong seismic activity of nearby Klyuchevskoy volcano obscured the seismicity of Bezymianny, which likely remains active with slow extrusion of its lava dome. Video data showed a moderate gas-steam activity of the volcano (KVERT).

Rabaul (Tavurvur) (New Britain, Papua New Guinea): Activity continues. The latest NOAA satellite image data shows increased SO2 emissions.

Ulawun (New Britain, Papua New Guinea): A relatively strong eruptive phase seems to be occurring at the volcano. An ash plume rose to 12,000 ft (3.6 km) altitude last evening and a significant SO2 plume is visible on satellite data.

Batu Tara (Sunda Islands, Indonesia): Relatively frequent larger strombolian to vulcanian explosions continue to produce ash plumes regularly spotted on satellite data. The ash plumes reach altitudes of about 7,000 ft (2.1 km).

Dukono (Halmahera): Ash emissions have been seen on satellite data during the past days, confirming significant ongoing explosive activity.

Copahue (Chile/Argentina): New ash emissions started last night. The increase of activity also manifested itself in visible incandescence since the night of 26-27 Sep. The volcano had been quiet since the last time similar ash emissions and some incandescence were spotted in mid August. Sernageomin has not (yet) commented on this new activity.

We truly love working to bring you the latest volcano and earthquake data from around the world. Maintaining our website and our free apps does require, however, considerable time and resources.
We need financing to increase hard- and software capacity as well as support our editor team. We're aiming to achieve uninterrupted service wherever an earthquake or volcano eruption unfolds, and your donations can make it happen! Every donation will be highly appreciated. If you find the information useful and would like to support our team in integrating further features, write great content, and in upgrading our soft- and hardware, please make a donation (PayPal or Online credit card payment).

Planned features:
  • Improved multilanguage support
  • Tsunami alerts
  • Faster responsiveness
Thanks to your past donations, these features have been added recently:
  • Earthquake archive from 1900 onwards
  • Detailed quake stats
  • Additional seismic data sources
