More than 25,000 people were forced to evacuate following a series of eruptions of a volcano in Indonesia on January 11.

Mount Sinabung on the western island of Sumatra sent hot rocks and ash up to 5,000 metres in the air, Indonesia’s National Disaster Mitigation Agency emergency response director Tri Budiarto said.

No casualties have been recorded so far, he added.

However, he noted that lava flows destroyed thousands of hectares of crops, while smoke and ash seriously polluted surrounding villages.

The 2,457-metre mountain is one of the 129 active volcanoes in Indonesia.

It had been quiet for around 400 years until it rumbled back to life in 2010, and again in September last year.-VNA
