During the Merapi tragedy, many volunteers are helping and most of them are from students who many college/campus in Jogja. They are working together to provide shelters and consumptions demand needed by people whom was evacuated during Merapi eruption which caused them to abandon their houses.
Even though it's just a voluntarily actions, but what they did up to now must be given an appraisal. They didn't do it for money (some of them have to spend money on their own to help others) or fame (no one list all of the volunteers), but they do it because they wanted to help each others.
Salute to them Keep up the good work
