New interesting developments take place on La Réunion island, where the eruption has entered e new phase:
While visual lava emission from the vents in the Plaine des Osmondes at about 1600 m a.s.l. more or less stopped on the 24th, a large river of lava, believed to originate from accumulation beneath the flow field emerged from there on the afternoon of the 25th, travelling about 5 km in less than 2 hours down the Grandes Pentes (the steep ocean-side slope inside the horse-shoe-like open caldera), cutting the national road and entering the ocean.
From Thursday 24th on, shallow earthquakes appeared seismicity beneath Dolomieu crater on the summit of the volcano, increasing to a swarm with several hundreds of quakes up to magnitude 3 on Saturday 26th. This might be an indicator of the formation of a new pit crater.
At the same time, a new vent opened on the North East rift zone above "Bois Blanc" within the "Trou de Sable" on the northern boarder of the enclos at 450 m altitude. A new lava flow progressed within the enclos and stopped about 100 m above the national road. 
The volcano observatory warnes that an eruption "hors enclos" (outside the caldera) now should be considered a possibility within the next days. The area is being kept under under close surveillance.

Enjoying a break during a long hike (Bob, Phil, Tom, and Pam; l. to r.)
The two volcano tours on Hawai'i have come to an end, or better, the time to enjoy these fresh memories has now started. We look back on 10 days packed with impressions from exceptional activity at Kilauea volcano,- we have been incredibly lucky both as to activity (Kilauea was/still is in one of its most active phases since the start of the eruption in 1983), and the weather and last but not least thanks to the great mix of people we have had on board. Not only got we to see lots of lava during the 5 days each, but we also had our great share of fun, met interesting new people from all over and did many other interesting and nice activities aside.Tom took many photos, some of which will soon be available (mainly on www.decadevolcano.net). Due to the sucess of the tour, the VolcanoDiscovery Hawai'i team (Tom, Phil and Philippe) can offer to repeat the tour for individuals or small groups at almost any date on request, in English and/or French as well as Portuguese. In addition, two new fixed dates, now open for inscriptions, are now set up for mid November: 13-18 and 20-25 November, 2005. Details of the tour can be found at this page. (Since Tom will be on location as well during these tours, the languages the tour can be done, are: German, English, French, Danish, Italian, Greek and Portuguese or a mix of these). ...

Kilauea is erupting a lot of lava and the expedition is a huge sucess (so far)... Two active ocean entries, uncountable breakouts on the flowfield and the upper slopes as well as an intense activity at and around the Pu'u O'o cone are present. Tom and his small group are on location,- more photos and reports will be posted when time permitting. ... Lees alle
