BackgroundThe San Pablo volcanic field contains dozens of scoria cones and maars. 3 generations of maars are present: the oldest are shallow and filled with sediment and the youngest still contain deep crater lakes.
Most of the vents in the volcanic field follow a NE-SW trend. According to local legends, the youngest explosion crater, the 1.2-km-wide Sampaloc Lake, was formed only about 500-700 years ago.
The highest point of the volcanic field is formed by the eroded Maquiling (Makiling) andesitic-to-rhyolitic stratovolcano. Maquiling still has a 480 m deep crater and several parasitic cones, maars. Many fumarole fields are found at its northern base and a geothermal project is located on the south flank of Maquiling volcano.
Laguna de Bay lake borders the town of Manila at its SE margin. The lake is a caldera that erupted ca. 47,000 year ago (radiocarbon dating of charcoal in a ash flow deposit).
