San Pablo Volcanic Field

Volcanic field · Philippines · 1090m

Alligator Lake, along the southern shore of Laguna de Bay, is one of a group of dozens of maars and scoria cones forming the San Pablo volcanic field (also known as the Laguna volcanic field). Three generations of maars are present, the youngest of which contain deep lakes. Many of the maars are located along a NE-SW trend. Local legends indicate that the most recent eruption occurred about 500-700 years ago at Sampaloc Lake, 17 km SE of Alligator Lake.

Geological summary

The San Pablo Volcanic Field, (also known as the Laguna Volcanic Field) lies at the southern end of Laguna de Bay, the largest lake on Luzon Island. The field contains dozens of scoria cones and maars. Three generations of maars are present, with the oldest being sediment-filled and the youngest containing deep lakes. Many of the maars are aligned along a NE-SW trend. Local legends suggest that the youngest maar, 1.2-km-wide Sampaloc Lake, was formed about 500-700 years ago. The high point of the field is the eroded Maquiling (Makiling) andesitic-to-rhyolitic stratovolcano, which has a deep crater whose floor is 480 m below its north rim. Maquiling has several cones, maars, and numerous thermal areas at its northern base; a geothermal project is located on the S flank.

From Wikipedia

The Laguna Volcanic Field, also known as the San Pablo Volcanic Field, is an active volcanic field in the Philippines, located between Laguna de Bay, Mount Banahaw volcano complex and Mount Malepunyo range. It is part of the larger Southwestern Luzon Volcanic Field (SWLVF). From Manila, it is about 50 kilometres (31 mi) southeast to Mount Makiling, its most prominent volcanic feature.
