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.

Kamchatka: Klyuchevskoy and Sheveluch

by

The Russian peninsular Kamchatka is the land of volcanoes. During our journey between 14th and 26th October 2013 Martin, Richard and Marc visited the active volcanoes Klyuchevskoy and Sheveluch. The former one erupted first time since 3 years. During its strongest phases the explosions from Klyuchevskoy were heard at a distance from 30 km. Lava fountains rose up to 1 km above the summit.

Sheveluch volcano shows slight dome growth, accompanied by lava avalanches and small pyroclastic flows. One day before we reached the volcano, there was a bigger eruption with ash clouds up to 10 km altitude.
