Paekdu Volcano (North Korea)

Satellite data has indicated a swelling of Paekdu volcano in North Korea. The volcano increased by 18mm in the 6 years from 1992 to 1998. This indicates the volcano may not be completely dormant, and magma may be active under the mountain. More tests and observations will be needed to determine if the volcano is still inflating. The increase in height doesn't mean the mountain is seismically active. Paekdu volcano last erupted in 1702.

Manam Volcano (Papua New Guinea)

The government of New Zealand has increased its funding to the victims of Manam volcano disaster to US$680,000. Ten thousand people were evacuated from Manam Island at the end of 2004 after large eruptions made the island uninhabitable. The evacuees are located on the mainland of New Guinea, and face many problems, including lack of fishing grounds, malnutrition, and insufficient housing and medical care. International assistance will be required for years, while land issues are resolved and the islanders are resettled permanently. Evacuees from the 1996 eruptions have still not been adequately resettled, and live in poor conditions on the mainland. Low level activity continues at Manam Volcano.

Talang Volcano (Indonesia)

A phreatic eruption occurred at Talang Volcano in Indonesia on 2-3 July. The eruption was preceeded by a blasting sound at the main crater on the southern side of the volcano. Grey ash reached 300-500 m, and fell around Kampung Batu, which is located 2 km south of the summit. At the same time, Gabuo Atas crater, Gabuo Bawah crater, and Kapundan Panjang crater, which are located at the northern slope, also emitted white-brown steam, as high as 300 m, 50 m, and 150 m. The temperature of Batu Bajanjang hot spring, located below the summit, is 41.9-61.3° C. People are advised to keep a distance of 1 km from eruption point. Renewed eruptions of Talang volcano in 2005 have been attributed to the great 2004 Sumatra earthquake and aftershocks. Talang volcano is on alert level 2 (4 being maximum).

Fukutoku-Okanoba Volcano (Japan)

An undersea eruption occurred at Fukutoku-Okanoba volcano in the volcano islands, SE of Japan. A column of steam rose 1000 m above the volcano. Observations from a helicopter flyover showed rock and mud rising to the surface. A one-kilometer area of water has turned brown-orange. Eruptions of Fukutoku-Okanoba volcano have previously formed a temporary island, but it is unknown if an island will form this time.
