Rescue workers are sifting through smoldering debris and thick mud in search of survivors a day after a volcano on Indonesia’s island of Flores erupted, killing at least nine people with its searing lava and ash.

Authorities in Indonesia have evacuated nearly 2,500 people from areas affected by the ongoing eruption of Mount Lewotobi Laki-laki on Flores Island in East Nusa Tenggara province, local media reported Wednesday.

The Indonesian government aims to evacuate at least 16,000 residents from villages around the active Mount Lewotobi Laki-laki volcano that erupted and killed nine people and damaged thousands of houses,
