Laguna Caldera is a potentially active volcanic caldera and a geographical depression in Rizal, Philippines . It is broadly elliptical in shape, with dimensions of 20 by 10 km. It has a summit elevation of 743 m or 2,438 feet.[1] The caldera forms the middle lobe of Laguna de Bay, bound by the Morong Peninsula and Talim Island to the west, and the Jalajala Peninsula to the east.

The caldera may have formed in two stages about 1 million and 27,000-29,000 years ago, during which time at least two major explosive eruptions took place. It is unknown when the Laguna Caldera last erupted but it may have been active during the Holocene.[1] Deposits from the caldera form thick ignimbrite sheets in Rizal, Metro Manila, Laguna, and Bulacan.[2] Remnants of volcanic activity include undated maars at the southern end of Talim Island and a solfatara field on nearby Mount Sembrano.[1]
