The Aguas Zarcas group of nine basaltic cinder cones, located on the far northern flank of the Platanar-Porvenir complex to as low as 160 m altitude, is in part Holocene in age.  These cones lie 10-17 km behind the volcanic front of Costa Rica at a point 125 km above the Wadati-Benioff zone.  The pyroclastic cones were constructed along two parallel fractures striking NNW.
