On 10 February 2017 at 10:03 PM Philippine Standard Time (PST), a magnitude (M5) 6.7 earthquake struck the Province of Surigao del Norte in northeastern Mindanao. Using the data from the Philippine Seismic Network (PSN) of the Philippine Institute of Volcanology and Seismology - Department of Science and Technology (PHIVOLCS-DOST), the epicenter was located in Surigao Strait at 9.80° N and 125.35° E or 16 km offshore northwest of Surigao City at a shallow depth of 10 km. The earthquake was generated by the movement of the Philippine Fault - Surigao segment. The ground shaking was felt at PHIVOLCS Earthquake Intensity Scale (PEIS) VII in Surigao City and San Francisco. The rest of the municipalities in Surigao del Norte experienced PEIS VI to IV. Small magnitude earthquakes followed afterwards. As of 22 February 2017 8:00 AM, 230 aftershocks were recorded by the PSN, 106 of which were plotted and 26 were reportedly felt. The largest aftershock was recorded on 14 February 2017 at 4:03 AM with a magnitude of (M5) 5.0 and was felt in Surigao City at PEIS V.
This earthquake generated a 4.3 km surface-rupture that was mapped in Brgy. Ipil in Surigao City and Brgys. Poblacion, Honrado and Macopa in the Municipality of San Francisco, Surigao del Norte.
These barangays were estimated to experience strong ground shaking at PEIS VIII.
