Map of today’s active volcanoes

Reykjanes (Reykjanes peninsula (SW Iceland)): (5 Apr) The eruption continues from two active craters and remains essentially unchanged since the last update.
The larger, northern cinder cone appears to feed most of the lava flow by layering previous lava flow beds from the eruption’s first days. Fresh and molten pyroclasts continue to eject from edifices, resulting from continuous spattering that thickens the lava flow field in their vicinity rather than its length.

GPS statistics showed that the ground has been bulged by 3 cm during 18 March-3 April period.
The IMO added: „If you look at the GPS measurements over the entire period that the wave interpolation shows, you can see that there is consistency in the results of both measurements. It is an indication that the system is open and magma continues to flow from a great depth under Svartsengi and from there to the surface in the Sundhnúks crater series.“

Ebeko (Paramushir Island): (4 Apr) Volcanic Ash Advisory Center Tokyo (VAAC) issued the following report: ERUPTION AT 20240404/2039Z FL100 EXTD E REPORTED OBS VA DTG:04/2040Z

Semeru (East Java, Indonesia): (5 Apr) Volcanic Ash Advisory Center Darwin (VAAC) issued the following report: VA REPORTED TO FL150 AT 05/0115Z EST VA DTG:05/0250Z

Spurr (Cook Inlet, SW Alaska): (5 Apr) The Alaska Volcano Observatory (AVO) informed that the seismic station and remote webcam (approx. 75 miles from west of Anchorage) started to receive signals from the volcano again as conditions have enhanced.
Thick winter snow accumulation hindered the transmission of seismic data from stations on the volcano to the AVO volcano observatory based in Anchorage.

Recent improvements in conditions at the volcano, coupled with maintenance work at the Anchorage receive facility and adjustments to remote radio configurations, have enabled AVO to consistently collect data from six stations within the Spurr Network. Consequently, AVO can now monitor volcanic activity in real-time and issue timely warnings of potential eruptions.

Fuego (Guatemala): (5 Apr) Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Washington warned about a volcanic ash plume that rose up to estimated 14000 ft (4300 m) altitude or flight level 140 .
The full report is as follows: VA EM CONT to 14000 ft (4300 m)

Nevado del Ruiz (Colombia): (4 Apr) Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Washington warned about a volcanic ash plume that rose up to estimated 23000 ft (7000 m) altitude or flight level 230 .
The full report is as follows: NEW VA OBSD to 23000 ft (7000 m)

Reventador (Ecuador): (4 Apr) Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Washington warned about a volcanic ash plume that rose up to estimated 14000 ft (4300 m) altitude or flight level 140 .
The full report is as follows: RPRT OF VA EM to 14000 ft (4300 m)
