It was felt as a “moderately strong” tremor at Intensity IV in Rosario, Agusan del Sur and Maco, Davao de Oro, while it was “slightly weak” at Intensity II in Bayugan City, Agusan del Sur.
Phivolcs’ instruments also recorded the quake at Intensity II in Bislig City, Surigao del Sur and Intensity I in Davao City.
