Platanar Volcano is located in the Cordillera Central mountain range. It is part of a complex that covers {{convert|900|km2|acre}} and is dominated by Porvenir Volcano at {{convert|2267|m|abbr=on}}. It is located within the Juan Castro Blanco National Park.
Physical aspects
It has a destroyed crater to the northwest.{{cite book|author1=Guillermo E. Alvarado Induni|author2=Oscar Luis Chavarría-Aguilar, Guillermo E Alvarado Induni|title=Costa Rica: Land of Volcanoes|url=https://books.google.com/books?id=4ZCLTTcRIhIC&pg=PA144|year=2005|publisher=EUNED|isbn=978-9968-31-366-7|pages=144–}} Prehistoric lava flows on its western flank; one of them, the so-called Florida flow, was perhaps created by Platanar's most recent activity. Cerro Porvenir has a truncated caldera at the summit with a cone inside. Both of these are part of a composed stratovolcano of Upper Pleistocene age that on Platanar's side overlies the remains of Palmera's collapsed caldera, of probable late Pleistocene age.{{cite book|author=Jean Pierre Bergoeing|title=Geomorphology of Central America: A Syngenetic Perspective|url=https://books.google.com/books?id=TWwZBgAAQBAJ&pg=PA97|date=15 June 2015|publisher=Elsevier Science|isbn=978-0-12-803185-8|pages=97–}} Platanar has erupted lavas ranging from basalts to andesites in composition.
Social and economic activities
The western flanks of both volcanoes are used for dairy farming.{{cite book|author=Hans Otto Spielmann|title=Viehwirtschaft in Costa Rica: Struktur, Entwicklund und Stellung der Rinderhaltung in einem tropischen Entiwicklungsland|url=https://books.google.com/books?id=Ni9BAAAAYAAJ|year=1969|publisher=Ludke bei der Uni|page=210|language=de}} In 1968 {{convert|2500|ha|acre}} on Cerro Platanar were converted into a National Forest.{{cite book|author=Centro Nacional de Acción Pastoral (Costa Rica)|title=La Montaña sagrada: una lucha por la vida|url=https://books.google.com/books?id=Az4sAAAAMAAJ|year=1990|publisher=Centro Nacional de Acción Pastoral|language=es|page=17|isbn=978-9977-78-009-2 }}
Recent activity
On 30 March 1997 there were six earthquakes on the south flank, the strongest being of magnitude 2.7. A previous seismic swarm in April 1980 had lasted for 2–3 weeks.{{cite gvp|vn=vn=345034&vtab=Weekly|name=Platanar-Bulletin Report|accessdate=10 June 2015}}
