A COMVOL investigation has determined that press reports of hot mudflows at Babuyan Claro were incorrect. COMVOL found that a landslide, probably triggered by continuous rainfall, had occurred at 600 m above sea level on the NW flank.
Geologic Background. Five Pleistocene-to-Holocene volcanic centers occupy Babuyan de Claro Island north of Luzon. The largest edifice is Mt. Pangasun (Babuyan Claro), an active stratovolcano with two summit craters 300 and 400 m in diameter. The symmetrical basaltic andesite cinder cone of Smith Volcano (Mount Babuyan), located 4 km NW of Babuyan Claro, is the youngest volcano on the island. Both Babuyan Claro and Smith have apparently been active in historical time, although the identity of the erupting volcano is not always certain. Askedna Hot Spring is located at the southern base of Babuyan Claro.
