Towns and Landscape of Taal Volcano and its Calder by Boj
Taal Volcano - nominated for criteria (vii) (viii) and (x). Its OUV cannot be denied; even the 2009 IUCN Thematic study on World Heritage Volcanoes (https://portals.iucn.org/library/efiles/edocs/2009-065.pdf) mentions how it can easily fill in the "resurgent caldera" category, i.e., a "Matryoshka doll" type of volcano - a crater within a crater within a crater. It is indeed a remarkable sight!
The sad reality is that the urbanization of towns surrounding the Taal volcanic lake is starting to compromise the visual integrity of the landscape.
Moving on with the subject of heritage volcanoes, two more Philippine volcanoes - Mayon and Pinatubo - equally deserve attention.
