Karangetang Volcano (Indonesia)
2.47 N, 125.29 E, summit elevation 1784 m, stratovolcano
Wednesday 26th July 2006
Karangetang volcano in Indonesia has been placed on maximum level 4 alert since 22nd July. Visual observations were not possible today due to fog, but seismometers are recording volcanic tremor. Villagers close to the volcano have been warned about the possibility of pyroclastic flows, and advised to stay away from the crater. The regional government is preparing to evacuate residents. Rain will create mudflow hazards at the volcano. The Directorate of Volcanology and Geological Hazard Mitigation in Indonesia says a large eruption is possible. In April 2006 a magnitude 6 earthquake hit Karangetang volcano.

Kilauea Volcano (Hawaii)
19.425 N, 155.292 W,, summit elevation 1222 m, Shield volcano
Sunday 2nd July 2006
A new surface lava flow is visible at Kilauea volcano in Hawaii. The lava flow begins at the Campout lava tube at an elevation of 2300 ft, and descends to 800 ft elevation. The flow is burning trees, and is solidifying to `a`a lava, which is less common than pahoehoe flows which are usually seen at the volcano. Lava continues to enter the sea at East Lae`apuki, fed by the main PKK lava tube. The lava delta at the ocean entry has reached 22 hectares in size since the coastal collapse in November 2005.
