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.
