Source: Volcano Discovery Akita-Komaga-take (Honshu): Elevated seismic activity has been detected by Japanese volcanologists. No other parameters (visual fumarolic activity, deformation etc) seem to be above background levels and no particular alert was raised. Colima (Western Mexico): Mild explosive activity continues from the volcano. Mostly small explosions occur at irregular intervals of typically several hours…

Source: Volcano Discovery Etna (Sicily, Italy): INGV Catania published the result of very high-resolution satellite-based measurements of ground deformation of Etna during the period between Feb 2015-Feb 2016. They show that Etna’s dominant trend of deformation has changed from inflation (in blue) to deflation since the latest eruption in early December.   Inflation of the…

Source: Volcano Discovery Shishaldin (Aleutian Islands, Alaska): The alert level was lowered back to normal status. Detectable activity (visible observations and satellite-based data) has been decreasing steadily of the past several months, the Alaska Volcano Observatory reported: “There has been a steady decrease in detected thermal activity at Shishaldin over the past several months. No…

Source: Volcano Discovery Nevado del Ruiz (Colombia): A series of small explosions occurred at the volcano yesterday. The first happened in the afternoon at 16:32 local time. The Manizales volcano observatory recorded a pulse in tremor and reported an ash plume that rose 1300 m above the summit. Similar explosions with ash emissions could be…

  Source: Volcano Discovery Sinabung (Sumatra, Indonesia): Explosions and generally small pyroclastic flows, sometimes happening together, continue to occur at the volcano at rates of a few per day on average. Yesterday evening 17:55 local time, an explosion produced a plume that rose 2.3 km and a pyroclastic flow that traveled 1.5 km. Dukono (Halmahera):…

Suwanose-jima (Ryukyu Islands): (8 Mar) The eruptive activity at the remote Island in southern Japan continues. It even seems to have picked up in intensity, judging from the increasingly frequent volcanic ash reports issued by Tokyo VAAC and the sometimes very strong glow visible from neighboring islands. The exact type of activity in the Otake…

Shiveluch (Kamchatka): The lava dome continues to be very active, generating frequent rockfalls and small glowing avalanches on the SW side as well as, more rarely, on the SE side as can be seen on today’s time-lapse video: A larger event might have taken place after dark, as Tokyo VAAC reported an ash plume to…

Alaid (Northern Kuriles): A new eruption is occurring at the volcano, satellite images show. A pronounced steam plume with possible ash content can be seen drifting west from the volcano, at estimated 13,000 ft (4 km) altitude. In addition, NASA’s MODIS and VIIRS sensors have been detecting an intense heat source from the volcano’s summit…

Bagana (Bougainville Island, Papua New Guinea): Based on Himawari-8 satellite data, Darwin VAAC reported an ash emission from the volcano at 7,000 ft (2.1 km) altitude last evening, creating a plume that drifted 100 km to the NE. Aviation color code is at Orange. Kilauea (Hawai’i): The activity of the volcano remains essentially unchanged. Rising…

Suwanose-jima (Ryukyu Islands): After a period of relative calm since last October, a new phase of strombolian activity occurred this morning at the volcano. Time-lapse video from Sinabung (Sumatra, Indonesia): The activity of the volcano seems to have picked up. Our correspondent Andi who’s there on one of our Volcano Special tours, reported: “Sinabung increases…
