Increased activity was recorded by PHIVOLCS in September, starting with a series of volcano-tectonic earthquakes on September 9. [13] On September 10, Kanlaon produced its highest volume of sulfur dioxide emissions since 2009, at 9,985 tonnes, prompting PHIVOLCS to raise concern over its possible first magmatic eruption since 1902.

[8] The seismological arm of PAGASA was officially transferred to PHIVOLC [9] on September 17, 1984 through Executive Order No. 984, renaming the institute as the Philippines Institute of Volcanology and Seismology or PHIVOLCS. [10] The NSTA, the umbrella department for PHIVOLCS and PAGASA, became the Department of Science and Technology (DOST ...
Eruptions were recorded from 1886 to 2006. On November 23, 2015 the volcano had a small, steam-driven explosion. PHIVOLCS raised the alert level to 1 (mild restiveness). Last eruption was on December 9, 2024 which PHIVOLCS classified as phreatic eruption. Kanlaon ejected about 3 kilometers high column of pyroclastic ash and incandescent materials.
Kanlaon, also known as Mount Kanlaon and Kanlaon Volcano (Hiligaynon: Bolkang Kanglaon; Cebuano: Bolkang Kanglaon; Filipino: Bulkang Kanlaon), is an active andesitic stratovolcano and the highest mountain on the island of Negros in the Philippines, as well as the highest peak in the Visayas, with an elevation of 2,465 m (8,087 ft) above sea level.

The Philippine Institute of Volcanology and Seismology (PHIVOLCS) initially reported a magnitude 6.5 earthquake striking at 8:03 am Philippine Standard Time (PST) in Cataingan, Masbate. [9]
The PHIVOLCS listing is the basis of this list, but with additional information, some were reclassified in the active list or the potentially active list. Volcanoes with solfataric or fumarolic activity indicating active magma supply such as Pocdol Mountains , are placed in the List of potentially active volcanoes in the Philippines .
The Philippine Institute of Volcanology and Seismology (PHIVOLCS) said it had a magnitude of 7.4 and that it measured VII (Destructive) on the PHIVOLCS earthquake intensity scale in Tandag. [8] The earthquake occurred as a result of shallow oblique-thrust faulting likely along the subduction interface of the Philippine Trench.
