Timelapse footage shows Kanlaon Volcano emitting thick ash plumes in the Philippines.

Authorities said that the greyish plumes rose above the crater to heights of 164 to 246 ft (50 to 75 m) in Canlaon City on December 16.

Local media reported that residents in the southern area of the volcano would experience ashfall.

Thousands of families were displaced by the disaster, prompting the government to urge residents to evacuate.

The Philippine Institute of Volcanology and Seismology (PHIVOLCS) warned of potential lava flows in rivers passing through towns affected by Pyroclastic Density Currents (PDCs).

During a press conference, a spokesperson said: 'Mount Kanlaon emitted a 2.5-mile (4 km) ash column above the crater and a deadly spurt of hot ash, gases, and fragmented volcanic rock about 2 miles (approximately 3 km) down the mountain's southeast flank.'

PHILVOLCS raised the alert level to 3 in Negros Island on December 9 due to observed magma movement.
The institute advised local government units to evacuate residents within a six-kilometer radius of the summit and to be prepared for additional evacuations if necessary.

Kanlaon is one of the 24 active volcanoes in the Philippines.

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