Global Volcanism Program | Image GVP-11147
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.
