Piton de la Fournaise volcano (La Réunion), activity update: summit crater collapses
As had been forecasted by scientists, the summit of Piton de la Fournaise volcano has collapsed today (7 April). Practically all of the interior of Dolomieu crater has collapsed into a new pit crater with vertical walls and 300 m depth, with an estimated collapse volume of 50 million cubic meters.
The activity has been accompanied by strong earthquakes beneath the summit and produced dense ash clouds. At present, seismic activity continues in the area below the summit; further collapse could happen in the near future.
The series of events at Piton de la Fournaise marks one of the largest pit craters to be formed ever observed in historic time on a volcano.
In the meanwhile, lava emission at extremely high rates from the eruptive fissure continues.
We gladly announce two new study&walking tours we can offer you in Italy: one to the Bay of Naples from 8-15 April and a two-weeks tour of the Eolian Islands from 6-18 May 2007. Both tours will be guided by our Italian geologist Marta who is a true insider in both areas.[meer...]
Because of the recent interesting volcanic activity at Merapi and Semeru volcano on Java, we point to two tours with open spaces for last-minute individual bookings:... [meer...]
Due to lack of participants, we decided to cancel the tour to North Sulawesi and postpone it to 2007. As an interesting alternative, we can offer a special trekking tour in Java and Bali from 5-20 August instead. There are two open spaces available.[meer...]
