Ubinas [SEP] 2006–2007 eruption
The first episode of the 2006–2007 eruption sequence involved the ejection of large volcanic bombs at high speed and the emission of small quantities of ash. Gas and ash columns were emitted between April and October 2006 and reached heights of about . Volcanically induced melting of snow that had fallen on the summit during the 2006–2007 summer induced a mudflow in January 2007 that descended into the Ubinas River valley. Volcanic activity—degassing and of Vulcanian eruptions—decreased until late 2009. This eruption was probably triggered by the entry of fresh magma in the magma plumbing system and the subsequent interaction of ascending magmas with the hydrothermal system of Ubinas.
