Expédition à l'Erta Ale fév 2008 - fontaines de lave

Erta Ale volcano (Ethiopia) (2 gallerie)

L'activité principale du Krakatau au juin 2009 était strombolienne. Des explosions se poursuivaient à des intervaux de 2-5 minutes et jettaient des nombreuses bombes incandéscentes jusqu'une hauteur de plusieurs centaines de mètres.

En juillet 2009, l’activité du Stromboli était d’un niveau normal à élevé, avec des éruptions stromboliennes typique des bouches NW, central et NE. Les photos ici ont été prises, le 8 et 14 juillet pendant des conditions météorologiques exceptionnellement clair (vent levante et scirocco) au sommet.

The following photos show the activity inside the Pu'u 'O'o vent during 13-20 July, when intermittent vents were active inside the cone, forming lava flows and temporary lava lakes.

Until June 2007, lava was flowing into the sea. Here are some impressions taken during a visit on the island in April 2007.

Spattering from a vent feeding the eastern lava lake. The vent corresponds to the former East Pond vent in Pu'u O'o. During the time the photos were taken, the hornito above the vent collapsed, allowing a view onto the boiling lava.

We present you some photos from the lava lake occupying the eastern part of Pu'u 'O'o crater on Kilauea volcano, Hawaii, taken during 14-20 July 2007.

The most frequent type of activity was ash venting, occuring at intervals of typically 2 minutes, but the resulting plumes were relatively low ash clouds. Some of the more powerful explosions produced tall plumes of over 1 km height.

During 17-19 January, we managed to stay on top of Lengai with a small group. During much of the time, the summit was in clouds, but on 18 January, the afternoon proved to be clear and Lengai started a phase of ash eruptions lasting from around 4pm to 8pm. A detailed report about the expedition and Lengai's acitivity in the time between 17 and 21 January can be found <link 1508>here</link>.

After the powerful paroxysm at South East Crater on 10 May 2008, a spectacular fissure eruption started on 13 May, opening a 1000 m long, E-W trending fissure starting at the base of the SE crater, and extending into the upper flanks of Valle del Bove.
The activity started with impressive ground deformation where the advancing dike openend the ground, hurling out blocks of older material, some more than tens of meters across. At the fissure, curtains of fire fountains formed from at least 15 vents and produced a fluid lava flow that quickly descended into Valle del Bove. After about one day, the eruption waned quickly to stabilize into mild strombolian activity from a few vents on the upper part of the fissure between 2800 and 2900m.a.s.l. This activity prevailed when our team visited the eruption sites between 15 and 24 May, which is documented in the following photos.

We decided to revisit Anak Krakatau in early July. Its activity of Anak Krakatau was still moderately strong, although individual explosions only occurred at intervals between 1-4 hrs. Generally, eruptions were more ash-rich than in November, these eruptions were rich in ash, with frequent small lightnings in the ash plumes that reached up to about 1 km height.

Une éruption spectaculaire et dangereuse s'est manifestée au Merpi au 2006. Nous vous prensentons des fotos de l'éruption prises pendant une expédition au mai 2006. L'éruption produisait des coulées pyroclastiques.
