Felt intensity is the ground shaking actually felt and reported by the people through the Phivolcs Earthquake Intensity Scale, while instrumental intensity was indicated by the ground shaking intensity measured by the intensity meters in and around the epicentral area.
Phivolcs said damages and aftershocks are expected but assured there was no tsunami threat from this earthquake, which hit an offshore area of Davao Occidental.
However, earthquakes of this size may generate unusual sea level disturbances that may be observed along the coasts near the quake’s epicenter of Davao Occidental, according to Phivolcs.
