The explosion earthquake was felt by people at Srumbung village, 12 km from the volcano. At 0:35 hr yesterday there was a large pyroclastic flow recorded which lasted for 22 minutes, and flowed in the direction of K. Gendol, K. Kuning, K. Krasak, and K. Boyong. At 0:16 hours yesterday a pyroclastic flow lasted 7 minutes and flowed towards K. Lamat, K. Senowo, and K. Krasak. The Center of Volcanology and Geological Hazard Mitigation in Indonesia reports that a major eruption is possible.

Piton de la Fournaise Volcano, Reunion - John Seach

Renewed activity occurred at Piton de la Fournaise volcano, Reunion on Wednesday 27th October. Seismic activity increased sharply at 14:30 hours, which was four times the intensity of the preceding days. Volcano-tectonic earthquakes were recorded, which indicated new magma injection into the system. This was followed by new eruptions from a cone on the southeast flank of the volcano, and a lava flows at its base. A significant increase in tremor and new eruptive activity may suggest the beginning of a second eruptive phase at the volcano beginning on 27th October.

Merapi Volcano, Indonesia - John Seach

A new eruption occurred at Merapi volcano, Indonesia at 4:30 pm on 28th October. Darwin Volcanic Ash Advisory Centre reported that a high level eruption was observed from the ground. The eruptions this week have been explosive which is different from that experienced in recent times. The eruption of Merapi volcano on Tuesday produced a vertical blast which reached a height of 1.5 km. This is the first time that this type of eruption has been observed at the volcano. Eruptions of Merapi volcano during the 7–19th centuries A.D. were more violent than the past hundred years, and produced explosion pyroclastic flows. In 2001 scientists predicted that the quiet of the 20th century would be broken by a larger explosive eruption in the coming decades. It is possible that the eruption of Merapi on Tuesday was precipitated by the magnitude 7.7 Sumatran earthquake a few hours earlier. The last eruption of Merapi volcano in 2006 occurred soon after a nearby tectonic earthquake.

Piton de la Fournaise Volcano, Reunion - John Seach

An eruption began at Piton de la Fournaise volcano, Reunion at 7:10 pm (local time) on 14th October 2010. The eruption site was located at an elevation of 2000 m on the southern side of the volcano. The events have accelerated in the early afternoon. The seismic crisis (characterized by numerous earthquakes at the base of the volcano) began at 1:30 p.m.. It peaked at about 3 pm. A larger than average earthquake occurred at 2:50 pm, which resulted in collapse of the inner walls of Dolomieu crater. The seismic crisis, which reflects the rise of magma in the volcano edifice, has slowed after 3 pm. According to information provided by the Volcano Observatory, the eruption took place near the site known as "Château-Fort".
