Earlier in April, I spent some time in the Karo Batak region of North Sumatra with some of my students. We talked with residents in the refugee camps displaced by the previous eruptions of Mt. Sinabung. You can read about our experience here.
In the last week the volcano has erupted again. Although I am no longer in Indonesia, I guess there are still several thousand refugees (in April there were more than 5,000). Please pray for the people and families whose homes and crops have been destroyed and who cannot return home.
Look at some breathtaking photos from various sources here and get more information from the Smithsonian Institute Global Volcanism Project.
Below is my own photo, the closest I got to the volcano in April 2014, before the most recent eruption.
