Volcanoes Bromo, Merapi, Tungurahua calm down

09.12.2010, Age: 2932 days

The Indonesian authorities have graded down the alert level for Merapi and Bromo as eruptions are slowing down. Activity on the other side of the Pacific, at the Ecuadorian volcano Tungurahua, has decreased at the same time.

While the immediate danger of eruptions at Merapi has decreased, the Indonesian Volcanology and Geological Disaster Mitigation Center (PVMBG) warns that lahars and collapse of the cooling volcanic dome still threaten the local population. Several hundred people have died and 250,000 have been evacuated during the latest series of eruptions. Those returning to the area in next few weeks are confronted with extreme damages and have to find new ways to pick up their lives.

Eruptions from Bromo have had less of an impact since the volcano is sitting in the sparsely populated area of the Bromo-Tengger-Semeru National Park, a huge caldera containing several volcanoes. Although eruptions have not completely stopped, the PVMBG decided it would be safe enough to lower the alert staus from red alert while still maintaining a safety limit of two kilometres.

After heavy activity, last week, and evacuation of people from the area, Tungurahua in Ecuador has become more quiet, but is still throwing out ash and bombs.
