Worldwide Volcano News and Updates

Based on satellite images and ground reports from PVMBG, the Darwin VAAC reported that during 31 March-2 April and 4-5 April ash plumes from Kerinci rose to altitudes of 4.3-4.9 km (14,000-16,000 ft) a.s.l., and drifted NW, N, and E. Read all

KVERT reported strong gas-and-steam activity at Klyuchevskoy during 25 March-1 April. A weak thermal anomaly was detected over the volcano during 25 and 29-30 March. Strong Strombolian activity began at 2325 on 3 April, and satellite images on 5 April began registering a bright thermal anomaly. Read all

Based on analyses of satellite imagery, the Darwin VAAC reported that during 2-3 April ash plumes from Langila rose to an altitude of 2.1 km (7,000 ft) a.s.l. and drifted 35-65 km N NE, and E. Read all

AVO reported that the intensity of the eruption at Pavlof greatly decreased during 29-30 March, though a news article noted that ash from the eruption had caused more flights in and out of Yellowknife and Regina, Canada, to be cancelled. Elevated surface temperatures identified in satellite data and visual observations of low-level, intermittent ash plumes were noted during brief breaks in poor weather conditions. Seismicity remained elevated above background levels through 4 April, and was characterized by occasional short-duration tremor bursts. Read all

At 1200 on 30 March CENAPRED reported that during the previous 24 hours the seismic network at Popocatépetl recorded 179 emissions and four explosions. Ash plumes from the explosions rose as high as 3.5 km above the crater; ash from the explosions caused Puebla's airport to close from 2000 on 29 March to 0600 on 30 March. Read all

Based on satellite images and notices from the Guayaquil MWO, the Washington VAAC reported that on 1 April an ash plume from Sangay rose to an altitude of 6.7 km (22,000 ft) a.s.l. and drifted SW. The next day an ash plume rose to an altitude of 5.5 km (18,000 ft) a.s.l., and a continuing thermal anomaly was detected. Read all

OVDAS-SERNAGEOMIN reported that at 0750 on 3 April the seismic stations at Villarrica began recording more energetic volcanic tremor. In addition, the webcam recorded increased surficial activity characterized by Strombolian explosions and intensifying crater incandescence. The Alert Level was raised to Yellow (the second lowest level on a four-color scale) and the public was warned to stay outside of a 1-km radius around the crater and away from drainages. Read all

JMA reported that on 1 April an explosion at Aira Caldera's Sakurajima volcano generated an ash plume that rose 2 km above Showa's crater rim. An explosion at Minamidake summit crater also produced an ash plume which rose 800 m above its crater rim. Three of five explosions detected at Showa during 1-4 April generated ash plumes that rose as high as 3.5 km, and ejected tephra as far as 1,300 m. Read all

KVERT reported that moderate activity at Alaid continued during 25 March-1 April. Satellite images showed an intense daily thermal anomaly over the volcano. A gas-and-steam plume continaing minor amounts of ash drifted about 60 km S and SW during 26 and 30-31 March. Read all

SVERT reported that satellite images detected a thermal anomaly over Snow, a volcano of Chirpoi, during 29-30 March and 1 April. The Aviation Color Code remained at Yellow. Read all
