La Soufriere Volcano (Montserrat) - eruption update: dome growth continues
The lava dome of La Soufriere volcano on Montserrat continues its rapid growth. The large spine disintegrated last week and growth of the dome has continued in a northerly direction, reaching a height of approximately 950m.
The active lava lobe is shedding rockfalls and small pyroclastic flows to the west, north and east. A very vigorous gas vent was seen on the west side of the lava dome on Wednesday, above Gages valley. Small fumaroles were visible at the top of Gages valley and below the lava dome remnant that stands at the top of Gages Valley.
The seismic network recorded 282 rockfall signals, 72 long period – rockfall signals, 148 long period earthquakes, 2 volcano-tectonic and 2 hybrid earthquakes. Measured sulphur dioxide fluxes varied greatly but produced an overall average of 454 tonnes per day (t/d) for the week. The maximum was 1229 tonnes per day on 6 March.

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.[more]
Tom and Marco are just back home from our pilot tour to Nyiragongo volcano, which was very successful, so we plan to repeat the tour in July this year already. In the near future, we will post photos from the tour as well as details about the tour. Stay tuned!... [more]
