JERAYA, NORTH SUMATRA, INDONESIA - JANUARY 05: Hot lava runs down Mount Sinabung from a lava dome on January 5, 2014 in Karo District, North Sumatra, Indonesia. The number of displaced persons has increased to 20,000 in Western Indonesia as Mount Sinabung continues to spew ash and smoke after several eruptions since September. Eleven deaths have now been recorded as a result of the eruptions with hundreds more falling ill. Officials expect the number of evacuees to rise as volcanic activity remains high.
