Mount Arayat SRTM-1 relief map. Rock types are basalt and andesite. The only rocks reported to have been dated are 0.53 and 0.65 million-year-old basalts. [1] These predate the crater collapse and formation of the lava dome known as White Rock, which could have occurred in the last 2000 years.
The Marikina Valley fault system, also known as the Valley fault system (VFS), is a dominantly right-lateral strike-slip fault system in Luzon, Philippines. [2] It extends from Doña Remedios Trinidad, Bulacan in the north, running through the provinces of Rizal, the Metro Manila cities of Quezon, Marikina, Pasig, Taguig and Muntinlupa, and the provinces of Cavite and Laguna, before ending in ...
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.
Cabalian is classified by the Philippine Institute of Volcanology and Seismology (PHIVOLCS) as active with solfataric activity. Radiocarbon dating on a pyroclastic flow deposit from the volcano estimated that the last eruption was in 1820 +/- 30 years.
The Macolod Corridor is a northeast-trending zone of active volcanism situated at the junction of different tectonic elements in southwestern Luzon, Philippines.It is approximately 40 km wide and perpendicularly bisects the Luzon Volcanic Arc.
