GDACS Score
- On 7 April at 21:51 UTC (8 April at 5:51 local time), the Kanlaon volcano, located in the Negros Island region (western Visayas, central Philippines), erupted. The explosive eruption produced a plume that reached up to 4,000 meters above the vent, dispersing ash to the west and southwest. Pyroclastic flow occurred and descended the southern slopes within approximately 1 km of the crater, in the area of La Castellana (Negros Occidental province).
- The National Disaster Risk Reduction and Management Council (NDRRMC) reports, as of 9 April, more than 20,200 displaced people, of whom nearly 8,500 have been evacuated to 22 evacuation centres, with approximately 48,850 people affected across the Negros Island region and the neighbouring Western Visayas and Central Visayas regions.
- Alert level 3, indicating magmatic unrest, remains in effect for the volcano.

Updates on volcanic activity (Smithsonian)
The Smithsonian/USGS Weekly Volcanic Activity Report provides information about global volcanism on a weekly basis. Latest Kanlaon report has been published on 23 Apr 2025 18:43.
The Philippine Institute of Volcanology and Seismology (PHIVOLCS) reported continuing eruptive activity at Kanlaon during 16-22 April. The seismic network recorded 1-16 daily volcanic earthquakes and two periods of volcanic tremor (34 and 42 minutes long) on 15 April. Daily sulfur dioxide emissions ranged from 1,170 to 3,078 tonnes per day. Gas-and-steam emissions that occasionally contained ash generally rose as high as 200 m above the crater rim and drifted SW, W, and WNW. There were two ash emissions on 15 April (20 and 70 minutes long), and another on 20 April (31 minutes long); voluminous gas-and-ash plumes rose 600 m above the rim and drifted SW on 20 April. The Alert Level remained at 3 (on a scale of 0-5); the public was warned to stay 6 km away from the summit and pilots were warned not to fly close to the volcano.
