Authorities cleared lahar flow from Kanlaon Volcano after heavy rain in the Philippines.

Footage shows volunteers scooping up wet mud and ash that slid into La Castellana town in Negros Occidental on May 24.

Heavy equipment were also deployed to clean the debris-covered roads.

Officials said there were no casualties, but the lahar flow destroyed one house, damaged seven others, and left large cracks on a bridge.

Raul Fernandez, head of a task force that monitors Kanlaon Volcano's activity, said: 'We've seen large cracks on the Tamborong Bridge and so, the Department of Public Works and Highways will have to assess it first in terms of its structural integrity.'

Lahar is a fast-moving volcanic mudflow made of water, ash, and debris that rushes down a volcano's slopes.

Kanlaon had triggered evacuations when it spewed molten material early morning on May 13. It is one of the country's most active volcanoes and is currently under Alert Level 3, indicating 'increased chances for sudden and even stronger explosive eruptions'.

The Philippines, an archipelago of over 7,000 islands, lies within the Pacific Ring of Fire, a region known for frequent volcanic eruptions and earthquakes.
