Saturday 17th September 2005
Ilamatepec volcano has shown increased levels of activity since 27 August 2005. Hundreds of small earthquakes have been registered daily, and there is an increase in water temperature at the volcanic lake. The increased activity indicates magma is close to the surface. The Territorial Studies Service (SNET) of the Ministry of the Environment has declared a yellow alert for the volcano. The Salvadorean government has announced that it will begin carrying out evacuation simulations for the population living near the volcano in anticipation of an eruption. According to the National Emergency Operation Centre (COEN), several shelters have been opened in the area to attend to families that may need to be evacuated. The volcano is not currently erupting.

Kilauea Volcano (Hawaii)
19.425 N, 155.292 W,, summit elevation 1222 m, Shield volcano
Sunday 4th September 2005
More than 11 acres of land collapsed into the ocean at Kilauea volcano in Hawaii on 26-27 August. The collapse of East Lae`apuki lava delta was predicted for a few weeks, as cracks had appeared in the lava bench. Boulders up to 1 m in diameter were thrown onto the shore during the collapse. The bench collapse was 460 m long (parallel to shore) by 150 m wide (perpendicular to shore). Since August 27, lava has re-filled about 1.7 ha (4.25 acres) of the collapse area. Several streams of lava are pouring into the water off the East Lae`apuki delta.

Mayon Volcano (Philippines)
13.257 N, 123.685 E, summit elevation 2462 m, stratovolcano
Saturday 3rd September 2005
A six-kilometer permanent danger zone (PDZ) has been placed around Mayon Volcano, following the growth of the lava dome in the summit crater. The Philippine Institute of Volcanology and Seismology says that the volcano could be recharging with magma, and a new series of eruptions may not be far away. Currently the volume of lava in the crater is small. However, further emisson of lava could spill into the lower portion of the crater rim facing the southeast side of the mountain. Mayon volcano remains at level 2 alert.
