Indonesia's Mount Sinabung has erupted several times over the past few days, sending powerful blasts of hot ash and rock up to 10,000ft (3,000m) into the air. The eruptions have led to several potentially deadly pyroclastic flows, caused by the collapse of the dome of solid lava on top of the crater.
