Tungurahua volcano (Ecuador), activity update: continuing strong explosive activity
Tungurahua volcano continues with strong explosions producing eruption columns rising to 10-11 km and pyroclastic flows and lahars (mud-flows) on its flanks:
IG reported that on 27 March, at 1716, an ash column from Tungurahua rose to an altitude of 11 km (36,000 ft) a.s.l. An accompanying pyroclastic flow traveled 1 km down the Mandur gorge on the NW flank. A lahar traveled W down the Bilbao gorge and vibrated near-by structures. On 28 March, ash plumes again rose to altitudes of 11 km (36,000 ft) a.s.l. Ashfall was reported from areas downwind. Noises that resembled rolling blocks down the flanks were reported. Hot steaming mudflows traveled N, NW, and W. On 29 March, three explosions rattled windows in areas as far away as 8 km. During 30 March-3 April, ash plumes, occasionally accompanied by roaring noises and “cannon shots,” rose to altitudes of 6-10.5 km (19,700-34,400 ft) a.s.l. and drifted mainly W and NW. Incandescent material was ejected 300 m above the crater and subsequently descended about 1 m down the flank on 31 March; similar activity was observed at the summit during 1-2 April. Ashfall was reported from areas about 8 km SW, N, and W.

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.[more]
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:... [more]
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]
