The East Luzon Syntaxis. Faulting from Lagmay et al., (2005, 2009). Short thick lines indicate extensional faults, thinner lines are left-lateral transcurrent faults, dashed where based on interpretations of bathymetry. Red triangles are Late Neogene volcanoes, named where there is a record of historic eruption. The yellow dotted line marks the current consensus location of the main fault of the Philippine Fault System.
