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.

Local legends suggest that the latest eruption of the San Pablo volcanic field took place about 500-700 years ago, forming the Sampaloc Lake maar. This 1.2-km-wide maar, seen here from the S, is one of the largest of a group of 36 maars in the volcanic field.

The forested Maquiling volcano (center) rises south of Laguna de Bay (top) and is the highest point of the San Pablo volcanic field. It has a deep crater whose floor is 480 m below its N rim and several cones, maars, and numerous thermal areas at its northern base, and other maars and scoria cones of the San Pablo volcanic field lie to the E. The prominent dark-colored maar along the shore of Laguna de Bay north of Maquiling is Alligator Lake.

Lake-filled maars are common features of the San Pablo Volcanic Field at the southern end of the large Laguna de Bay (top). The monogenetic volcanic field contains a group of 42 scoria cones and 36 maars, the youngest of which contain deep lakes. The largest maar in this Landsat image is 1.2-km-wide Sampaloc Lake, immediately N of the city of San Pablo. Local legends suggest that this maar formed about 500-700 years ago. The forested volcano to the left is Maquiling.
