The tectonic quake struck 18 km. northeast of Bogo City at 5:39 a.m.

Meanwhile, intensity IV was felt in Bogo City, Cebu; Villaba, Tabango, and San Isidro, Leyte.
Intensity III was reported in Tabuelan, Cebu; Calubian and Palompon, Leyte, while intensity II was felt in Argao, Cebu.
Phivolcs also logged the following instrumental intensities:

Reported intensity is the traditional way of knowing the intensity based on reports by people who felt the earthquake.
