Worldwide Volcano News and Updates

Mild, typical strombolian activity has established itself inside the Mackenney crater. "Dry" (not containing much ash) explosions occur frequently and eject incandescent scoria to about 25 m height above the crater and an intra-crater cone, now about 15 m high, is being formed inside the crater. Some of the explosions can be heard in up to 5 km distance. At night, glow can be seen from the crater.

Seismic activity has picked up, suggesting that the volcano could be headed for more vigorous activity soon. SO2 emissions on NOAA recent satellite data have been relatively high as well. Read all

Effusive and weak explosive activity continue. Volcanic tremor and small explosions continue to be detected in seismic data and satellite data continue to show elevated surface temperatures at the intracaldera cone. A light colored plume is rising above the cone to just above the rim of the caldera to about 8,000 to 10,000 feet above sea level and at night, a persistent glow is visible. (AVO)

The eruption had increased yesterday and produced ash plumes rising up to about 8.5 km (28,000 ft), but has decreased in strength again today. Read all

The group of our current trekking tour on Java climbed the summit of Anak Krakatau on 24 June. Climbing there was very difficult, because of many hot fumarolic spots and strong degassing. The summit of Anak Krakatau is now higher than before the Sep 2012 eruption. One active vent was remaining in the west part.

Based on analysis of satellite images, SVERT reported that steam-and-gas emissions from Chirinkotan were detected on 25 and 26 June. The Aviation Color Code remained at Yellow. Read all

According to news articles, ash plumes from Pavlof caused airlines to cancel one flight and reroute six more on 25 June. AVO reported that during 25-26 June seismicity declined, and consisted of intermittent bursts of tremor and occasional small explosions. Satellite images showed a plume containing small amounts of ash drifting NW, and strong thermal anomalies at the summit. Read all

Based on visual observations and analyses of satellite data, KVERT reported that during 21-28 June a viscous lava flow effused on the N flank of Shiveluch's lava dome, accompanied by hot avalanches, incandescence, and fumarolic activity. Read all

AVO reported that the ongoing low-level eruption of Veniaminof, characterized by lava effusion and emission of minor amounts of ash and steam, continued during 26 June-2 July, indicated by nearly continuous volcanic tremor and occasional small explosions detected by the seismic network. Satellite images showed elevated surface temperatures at the cinder cone inside the caldera consistent with lava effusion. During 26-30 June web camera images from Perryville (32 km SSE) showed a small light-colored plume rising above the cone to just above the rim of the caldera, and night time images showed persistent incandescence from the cone.

JMA reported that during 25-28 June Sakura-jima's Showa Crater had four explosions, ejecting tephra that fell at most 1.3 km from the crater. Crater incandescence was occasionally detected at night. Based on information from JMA, the Tokyo VAAC reported that on 26 June explosions were detected. Read all
