Added on 10 March:


AVO did not receive reports of activity at Korovin volcano in the Atka volcanic center after the original report of ash-and-steam emissions on 24 February. During 25 February to 4 March, cloud cover prohibited satellite views of the volcano and no unusual seismicity was registered.
----------------


26 Feb:


The Alaska Volcano Observatory (AVO) received a report of a minor ash and steam eruption from Korovin Volcano on Atka Island, Aleutian Islands, that produced an ash column of approximately 8,000 feet (2440m) above sea level. Since then, we have received no new reports of activity at Korovin Volcano. Cloud cover and generally difficult weather conditions make direkt observations as well as satellite cover near-impossible. The eruption at Korovin Volcano may be still developing.
Korovin Volcano presently is not being seismically monitored by a standard AVO seismic network. Korovin Volcano is a 1553 m high stratovolcano on the northern part of Atka Island in the central Aleutian Islands. The volcano has two distinct summit vents about 0.6 km apart, that have been the sites of eruptive activity as recently as June 1998. Korovin has erupted several times in the past 200 years, including 1907, 1951, 1953, 1954, 1973, 1976, 1986, 1987, 1996, and 1998. All of these eruptions produced minor amounts of ash and occasional but small lava flows. Reports of the height of the ash plume produced by the 1998 eruption ranged from 4900 to 9200 m (16,000 to 30,000 feet) above sea level.

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). ... lire toutes

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. ... lire toutes
