Hundreds of Indonesians fled their villages after a rumbling volcano spewed hot ash thousands of metres into the air and belched lava from its crater.
Mount Semeru on Java island spouted the towering column on ash on Tuesday, prompting a call for about 500 people to temporarily leave their homes.
Footage from the scene showed dead livestock covered by pyroclastic flows, a fast-moving mixture of hot gas and volcanic material, as steaming debris flowed into a river. There were no reports of injuries or deaths.
Indonesia is home to about 130 active volcanoes.
