Detailed explanation-2: -Data is sent to the PHIVOLCS Data Receiving Center (DRC) to determine earthquake parameters such as magnitude, depth of focus and epicenter. Together with reported felt intensities in the area (if any), earthquake information is released once these data are determined.

Detailed explanation-3: -On September 17, 1984, seismology or the science that deals with earthquakes, was transferred to the Institute from Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA).
