Classification

Follows the Philippine Institute of Volcanology and Seismology (PHIVOLCS) classification according to a volcano's eruptive history:

Active volcanoes

Erupted within historical times (within the last 600 years), accounts of these eruptions were documented by man erupted within the last 10,000 years based on the analyses of material from young volcanic deposits.

Potentially active volcanoes

Morphologically young-looking but with no historical or analytical records of eruption.

Inactive volcanoes

No recorded eruptions, physical form has been intensively weathered and eroded, bearing deep and long gullies.

Metadata

Metadata for each mountain can be parsed from the properties field.
