Paekdu Volcano (North Korea)
41.0 N, 128.08 E, summit elevation 2750 m, volcano type unknown
Thursday 21st July 2005
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)
4.10 S, 145.06 E, summit elevation 1807 m, Stratovolcano
Wednesday 13th July 2005
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)
0.97 S, 100.67 E, summit elevation 2896 m, stratovolcano
Thursday 7th July 2005
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).

Soufriere Hills Volcano (Montserrat)
16.72 N, 62.18 W, summit elevation 915 m, stratovolcano
Wednesday 6th July 2005
Volcanic activity remains elevated at Soufriere Hills volcano on Montserrat. Today, continuous ash emissions were reported at the volcano. Activity has remained high since the 20,000 ft high ash cloud recorded on Tuesday 28th June. The eruption last Tuesday came without warning, and produced pyroclastic flows which reached the sea along the Tar River. Next week (July 18) marks the 10th anniversary of the current eruption.

Colima Volcano (Mexico)
19.514 N,103.62 W, summit elevation 3850 m, Stratovolcano
Wednesday 6th July 2005
An explosion late on Tuesday night sent ash 5 km above Colima volcano in Mexico. The eruption was not as large as the spectacular explosions last month, but was larger than the well documented 1999 eruptions. The increasing activity may indicate that the volcano is entering a more explosive phase. In 1913, an eruption of Colima left a 500m deep crater and deposited ash on cities 385km away.

Renewed eruptions at Anatahan volcano in the Mariana Islands sent ash to 40,000 ft elevation. The six minute long paroxysm occurred at 4:46pm on Sunday, and was followed by long-period earthquakes and small explosions. The eruptions sent vog over Saipan and Tinian requiring a volcanic haze advisory to be issued Sunday night.
