Mount Iriga

Mount Iriga is a stratovolcano in the Bicol region that rises 1,196 meters above sea level with a base diameter of about 10 kilometers. The cone sits near Lake Buhi and forms part of a larger volcanic chain in the area.

The volcano erupted twice during the seventeenth century, in 1628 and 1642, representing its last recorded activity. Since then the mountain has remained dormant without any further volcanic events.

Local communities know this volcano by an alternative name, Mount Asog, which appears in their traditional stories and folklore. The mountain remains woven into how residents understand and relate to their landscape today.

Multiple hiking paths of varying difficulty lead up the slope, with starting points accessible through local communities in the area. Visitors should prepare for mountain conditions and check trail accessibility before heading out.

The volcano has a large crater formed by a debris avalanche event, creating a distinctive geological feature. This type of crater formation makes it geologically different from neighboring volcanoes.
