The document outlines definitions and classifications of volcanoes in the Philippines, identifying them as active, inactive, or extinct based on their eruption history. It lists notable active volcanoes like Mayon and Taal, while also describing examples of inactive and extinct volcanoes. Additionally, it discusses the implications and advantages of having volcanoes in the region.

volcano is
"sleeping," but it
could awaken in
the future.
