Merapi
Key Facts
-
-
-
410,000 in the vicinity of volcano became refugees, 367 killed and 277 injured.
130 million m3 of material destroyed crops, infrastructure, power lines and bridges.
Tectonic Setting
-
Much of Indonesia is an island arc formed by subduction of the Indo-Australian plate beneath the Eurasian plate.
To the East of the islands, the continental shift of northern Australia is in collision with the Eurasian plate.
Eruptive History
Highly active, eruption events in 1994, 1997, 2001 and 2006.
On each occasion, a dome developed in the crater which eventually collapsed, producing pyroclastic flows.

Social Impacts
Emergency shelter had to be moved 15km away. Lava flows closed off many roads and and others were closed for safety reasons.
Evacuation centres were overcrowded leading to poor sanitation, no privacy and a serious disease risk.

Environmental Impacts
Lahars were created due to ash, rocks and lava being washed down into towns by rainfall.
Water was contaminated with lava and ash and sulfur dioxide was blown across Indonesia all the way to Australia.
A conservation area has been set up around the volcano where it is not safe to live. Ash from the volcano eventually led to more fertile soils in the area.
Long Term Aid
2682 people had to be moved to new, safer houses permanently.
The government has set up a special task force to support people that have been affected by the volcano either by family issues or because they have lost their jobs.

Short Term Aid

1600 people were part of the national aid response (volunteers and military). International aid was offered from organisations like the Red Cross.
