The 4th eruption of Piton de la Fournaise volcano starting in 2005 ended "ufficially" on 19 January 2006, after eruptive and seismic activity had been gradually declining over the past weeks.

After several smaller explosions similar to the initial ones during the past days, Augustine Volcano seems to become even more active. Tuesday morning, an eruption produced an ash plume that reached 8 1/2 miles (ca. 13 km) height above sea level.

Half a month into 2006, eruptive activity at Pu`u `O`o continues unabated. Several vents within the crater continue to be active and glow is frequently visible on clear nights. Lava is still flowing through the PKK lava tube from Pu`u `O`o to the ocean, with a scattered surface breakout flows that are intermittendly active near Pu`u `O`o itself, on the steep slopes of Pulama pali, above the coastal plain, and just above the coastal plain before the lava enters the sea.

Two more explosions occurred from Augustine volcano on Jan. 12, 2006, producing ash plumes that rose to up to 5 miles (ca. 8 km) above sea level.

After 14 days in Greece, Tobias Schorr is back in office. The trip to the Saronic volcanoes was successful. The weather was great (4 days with sun and warm temperatures...). The trip was very special and surely one of the most beautyful winter trips to Greece. The islands of Poros, Aegina, Hydra and the peninsula of Methana have been visited. Many archaeologival and geological sites were on the routes. Soon the most beautyful photographs of this trip will be available on the VolcanoDiscovery homepage!
Augustine volcano has calmed down a bit, and the USGS lowered the alert level from RED to ORANGE. Seismic activity has declined since yesterday’s eruption but remains elevated above background and the volcano continues to steam vigorously. AVO reports steam and minor ash emissions from a new vent on the 1986 lava dome, producing a plume reaching an estimated height of 8000 to 10,000 ft (2400 to 3050 m) above sea level. Field observataions confirmed mudflows (also visible in the on-island web camera) on the flanks of the volcano. These flows are the likely source of false reports of new lava flows on the volcano....plus

Update: according to news sources, the eruption DID take place and an ash plume rose to a reported height of about 5 miles (8 km) into the sky. A weather service flight advisory was issued for pilots for an area 20 miles east and west of the volcano and about 50 miles north.

Fuego volcano is continuing to be in a more active phase compared to recent months, with moderate strombolian activity from the summit, several lava flows travelling down its flanks and occasional ash plumes up to 1-2 km height.
