Volcanism
The Babuyan Claro is one of 22 active volcanoes in the Philippines. It is classified as a stratovolcano and consists of four morphologically young volcanic buildings. Its highest point is 1,080 m of Mount Pangasun . West of Mount Pangasun there are 2 craters with a diameter of 300 and 400 m respectively, of which the lower crater has a height of 843 m. Other peaks are Cayonan in the south, Naydi and Dionisio in the southeast.
Is attached to the lower slopes in the south hot spring Askedna Hot Spring . The water temperature of this spring is between 44.6 ° C and 50.2 ° C. The water is slightly acidic and the silicon content is relatively high as the spring water flows through lava flows. The spring water is classified as "almost neutral sodium chloride brine ".
At the western end of Babuyan Island is the 679 m high cinder cone Smith Volcano , which had its last eruption in 1924.
outbreaks
Historical records report several eruptions of the volcano, including in 1652, 1831 (emission of around 550 million cubic meters of tephra), 1860, 1907, 1917, May 17-19, 1918, May 1919 and 1924. The eruptions were either Strombolian or phreatomagmatic nature.
In July 1993 earthquakes and an alleged drying out of the vegetation in the upper part of the slopes and in the summit area were reported. According to volcanologists , however, the earthquakes were tectonic in nature, and no significant change in volcanic activity could be detected.
In February 2004 there were reports of gray clouds of steam rising from the summit.
