Ongoing volcanic activity over the past year has kept thousands of residents away from their homes.
Officials say that as many as 10,447 people, or 3,143 families, are housed in 23 evacuation shelters, while another 3,683 evacuees live in houses provided by the government’s disaster agency.
A blast from Sinabung in February killed at least 16 people. Mount Sinabung surprised scientists in September 2010 by erupting suddenly for the first time in 400 years.
Two weeks of eruptions at that time forced more than 30,000 people from their homes.
