Physical Features

Babuyan Claro is classified by volcanologists as a stratovolcano
Stratovolcano
A stratovolcano, also known as a composite volcano, is a tall, conical volcano built up by many layers of hardened lava, tephra, pumice, and volcanic ash. Unlike shield volcanoes, stratovolcanoes are characterized by a steep profile and periodic, explosive eruptions...

 with an elevation of 843 m (2,766 ft) and a base diameter of 920 m (3,018 ft).

It has one hot spring

 called Askedna Hot Spring which is located at the southern basal slope of Babuyan Claro. It has a temperature range of 44.6 to 50.2°C. The water in Askedna hot spring is slightly acidic and the silica content is relatively high since the spring flows directly from lava flow deposits. The spring water can be classified as near-neutral sodium chloride

Babuyan Claro has four morphologically-fresh volcanic edifices: Mt. Cayonan in the south, Mt. Naydi and Mt. Dionisio in the southeast and Mt. Pangasun, a stratovolcano which has two very well-preserved craters 300 and 400 m in diameter.

Eruptions

Babuyan Claro has erupted on four occasions in historical times: in 1831, 1860, 1913 and 1917. All eruptions were either strombolian or phreatomagmatic.

In July 1993, there were reports of earthquakes and an alleged drying up of vegetation at the upper slopes and summit area of the volcano but volcanologist

s said the earthquakes were of tectonic origins and there was no significant change in the volcanic activity.

In February 2004, there were reports of grayish steam clouds hovering above the summit but volcanologists from the Philippines Institute of Volcanology and Seismology (Phivolcs) said the seismic swarm was of tectonic origin and the steaming activity was only wispy to weak.

Babuyan Claro is one of the Active volcanos in the Philippines and is part of the Pacific Ring of Fire
