The large Laguna de Bay is not simply a large lake. The middle lobe of its large edifice is in fact a massive caldera, which once produced pyroclastic flows that reached far beyond Manila. This Philippines volcano has been dormant for a long time, but could reawaken at some point in the future. One of its larger eruptions occurred 28,000 years ago, and was an order of magnitude larger than the recorded eruptions of Mount Pinatubo. This video will separate fact from fiction and discuss what size and duration of volcanic activity occurred at this vast caldera. I must note that this volcano may have erupted in the last 10,000 years, but the current evidence is inconclusive. Regardless, it is listed as a potentially active volcano.
