by

This volcano footage shows the eruption of Pico do Fogo in December 2014. The village Portela was destroyed by this eruption. The volcano is located on the Island Fogo. Fogo is one of the Cape Verde Islands and is of volcanic origin.

Bardarbunga: activity remains high

by
During last week, IMO maintained Aviation Colour Code Orange due to continued eruption at Bárdarbunga’s Holuhraun  fissure. Subsidence of the Bárdarbunga Caldera continued, and seismicity remained strong. Strongest earthquake under the central-volcano was M 5.4. The lava field was  more than 70 square kilometers on 9 November. Local air pollution from gas emissions persisted.

Sakura-jima: activity elevated

by

JMA reported that nine explosions from Showa Crater at Sakurajima volcano ejected tephra as far as 1,300 m during last week. An explosive eruption on 7 November generated an ash plume that rose 3.5 km. An eruption later that day from Minami-Dake Crater produced a plume that rose 1.4 km. The Alert Level remained at 3. The Tokyo VAAC reported that during 5-8 November plumes rose to altitudes of 2.1-4.6 km.

Kilauea: Lava flow is still active

by

The June 27th lava flow remains active. The flow front is 14.9 km (9.3 miles) from the vent, and 170 m from the Kaohe Homesteads boundary. The actual length of the flow, measured along the lava tube is 17.1 km. Between September 10 and 12 the advance rate dropped to approximately 250 meters per day. The flow front is still in thick forest, creating smoke, but fires are not spreading away from the flow. (Source: HVO)

Photo gallery: Dukono

by

The photos were taken between 10th and 14th June 2014 on the volcano Dukono. The volcano is located on the Indonesian island of Halmahera. The volcano is constantly active since 2008, but the intensity of the activity varies greatly. We caught the volcano in a very active phase: Volcanic ash rose up to 2.5 km high. At night we were able to observe volcanic lightning and strombolian eruptions. The eruptions hurled lava bombs  beyond the crater rim and presented a serious threat to the observers. Members of the expeditions were Thorsten Böckel, Richard Roscoe and Marc Szeglat.

Sinabung: pyroclastic flows

by

The eruption of Mount Sinabung started in September 2013, with series of small explosive eruptions. A  lava dome begun to grow in December and some weeks later first pyroclastic flows occurred. The Geonauts reached the volcano in mid-January 2014. We documented the eruption for one week. On some days the volcano was covered by clouds, or the activity was less. But during two nights we observed plenty pyroclastic flows. In some of them we observed volcanic lightning in the rising ash clouds. Most appeared in the night of the 14th January.

The village Sigarang Garang was very badly damaged by the eruption. Many roofs had collapsed under the weight of volcanic ash.

Etna: Paroxysm No. 16/2013

by

The paroxysmal eruption of Mount Etna appeared in the night between 16th and 17th November 2013. It was the 16th paroxysm this year. I travelled with the Geonauts Martin and Thorsten. We spend the night in our tents close to the rim of “Valle del Bove”, in a distance of 2 km to the active crater. The duration of the eruption was longer than it of most other paroxysm and less nearby all the night. Some spectacular lava bubbles were erupted. Two lava flows streamed to the southwest and southeast. These flows were not so long like others before.
