Kilauea Volcano (Hawaii)
19.425 N, 155.292 W, summit elevation 1222 m, Shield volcano
Wednesday 30th June 2004
A large deflation has been measured at Kilauea volcano during 28th June. At 0921 hr on Monday, deflation began at the summit caldera and Pu`u `O`o crater. At 1128 hr there was a marked increase in the rate of deflation at Pu`u `O`o which lost a total of 8.1 microradians. Numerous low frequency earthquakes and low-level tremor was measured beneath Kilauea'a summit caldera. This deflation of the volcano indicates that a large effusion of lava will possibly take place at the volcano, although nothing new has been observed so far.

Sunday 27th June 2004
Impressive lava flows were seen at Kilauea volcano on Saturday 26th June. Before dawn on Saturday, a large lava flow plunged down an ald sea cliff and moved across Wilipe`a delta. The lava tube system feeding the ocean entry has become blocked, and this caused the spectacular breakout seen yesterday.

Saturday 19th June 2004
Bezymianny volcano erupted at 08:40 local time on Saturday 19th June. The volcano sent up a colossal column of ash ten kilometers high, but the eruption poses no threat to local towns which are 40 km away. According to satellite data, ash plumes extended more than 200 km from the volcano at 00:19hr UT on June 19. At 02:39 UT on June 19, a large ash cloud moved to the north-northeast, in the direction of Bering Island. Volcanic earthquakes have been recorded at the volcano.

Kilauea Volcano (Hawaii)
19.425 N, 155.292 W, summit elevation 1222 m, Shield volcano
Friday 18th June 2004
Lava continues to enter the sea at Kilauea volcano. Multiple collapses have caused a 100m x 40m section of lava bench to fall into the sea. This highlights the danger of approaching the lava ocean entry too closely. Thich acidic steam marks the location of the collapses. The most active part of the flow is at the eastern delta.

Awu Volcano Indonesia
3.67 N, 125.50 E, summit elevation 1320 m, Stratovolcano
Sunday 13th June 2004
Vocanologists have downgraded the alert for Indonesia's Mount Awu volcano, saying it has cooled after an eruption last week that sent rocks 3,000 metres into the air. Officials say most of the 20-thousand people who fled their homes can now return. Only those living on the northern slope of the volcano are being told to stay away. The volcano may still reactivate at some time in the future.

Awu Volcano Indonesia
3.67 N, 125.50 E, summit elevation 1320 m, Stratovolcano
Saturday 12th June 2004
Mount Awu volcano in Indonesia's remote Sangihe island was quiet Friday, one day after a major eruption, although volcanologists warned of more possible activity. On Thursday, the 1,320-metre-high volcano erupted black smoke 3,000-metres into the sky and sent rocks and other volcanic materials from its crater. After Thursday's big eruption, Awu is only emitting white vapours from its crater. Although Awu's activity has declined, it does not mean the volcano has returned to normal. Data from seismographs over the past 24 hours shows some continuing seismic activity unser the volcano. More than 18,000 out of 28,000 residents living in danger zones around the Awu's slopes had been evacuated and temporarily sheltered in schools and churches in Tahuna, the main town on Sangihe, 15 kilometres from the volcano's crater.

Thursday 10th June 2004
Another eruption of hot ash occurred at Awu volcano on Wednesday 9th June at 5:12 am local time. Continuous small explosions are occurring and a column of ash is visible 2000m above the volcano. A magmatic eruption recorded on 7 June by the office of Vulcanology in Sangihe District and the Directorate of Vulcanology, caused the alert status to be raised to the maximum level (level 4- Red) on 6 June; with a prediction of a potentially large eruption at any time. Following instructions of the local government in Sangihe, the evacuation process commenced on the same day. Between 6 to 8 June, more than 17,000 people were evacuated (out of some 27,000 total vulnerable people - 12,065 from Tahuna, 5,690 from Kendahe, and 9,248 from Tabukan Utara). A major eruption killed 39 people in 1966; and displaced thousands of people from surrounding slopes.

Rocks and ash spread in a radius about 300 meters from the centre of crater. The ash blown by wind to the west west north and was detected at G.Kelud observatory. Many buildings in the nearby towns of Malang and Probolinggo were covered by a light coating of ash two hours after the eruption. The neighbouring towns of Lumajang and Pasuruan were also affected by the eruption. Mt Bromo is a popular tourist destination, and many visitors climb to the crater's edge.
