Mayon volcano started to erupt again on Dec 14. The lava dome in the summit of the steep stratovolcano began to grow again and is producing strombolian and vulcanian explosions as well as incandescent rock avalanches and small pyroclastic flows travelling down up to 3 km the SE side of the volcano. ...more [read all]

A new eruption started on Piton de la Fournaise volcano at 18h30 local time on 14 December. Following a seismic crisis lasting about 1 hr, a new vent opened on the S flank of Dolomieu Crater and produced lava flows inside the enclos. Later in the evening, a second fissure opened east of the first vent. ...more [read all]

At 1:58 AM on 11 Nov, an ash explosion occurred at the summit crater of Mayon Volcano. The event was not well observed as the summit was in clouds, but recorded on seismographs and iincandescent rock fragments were seen at the upper slope of the steep stratovolcano. Ashfall drifted towards the Southwest quadrant of the volcano due to the prevailing Northeast monsoon. [read all]

It seems that the activity reported from 6 November was not strombolian activity but rather the formation of a new collapse pit on the E flank of SE crater, explosing hot gasses and rocks that produced the glow visible on the webcams. Bad weather conditions have hampered inspections on site, but eruptive tremor is absent. However, Etna volcano could erupt any time as measurements indicate that the magma level inside the conduits is high. [read all]

Explosive activity at Anak Krakatau has resumed over the past weeks. Strong vulcanian-type eruptions from the growing lava dome in the new crater occur at intervals of 90-360 minutes as Yohannes one of our correspondants reports from a recent visit. Blocks are being thrown over the whole of the southern part of the island, including the forest and often reach the water as well. Small pyroclastic flows sometimes develop on the slope of the summit cone. The island must be regarded as an extremely dangerous place to be at the moment. Whoever visits the island should be aware of the risk of a sudden violent explosion, especially because there is little warning before an explosion and there are long intervals of quiet in between.
