"[The eruptions] must have been huge to produce such a big crater structure and that would have an effect on climate at the time; this would have been millions of years ago. One of their recommendations is to back up the existence of Apolaki and its related structures through a seismic reflection survey, a method similar to bathymetry that utilizes a seismograph to detect and record seismic activity through a receiver. The Philippine Rise is found and delimited within the West Philippine Basin, a sunken surface of oceanic crust at the location referred by its namesake, since the late Eocene epoch some 56 million to 33 million years ago.
