With the recent Bohol Earthquake (magnitude 7.2)  last October 15, 2013, people in Cagayan de Oro and Misamis Oriental are starting to be aware again about earthquake hazards.

The said Bohol earthquake was felt in Cagayan de Oro City (Intensity V). See screen capture of NDRRMC Report below. Download latest report HERE.

However, there were no reported damage as of 6:00AM today. Accordingly, local officials and government agencies are still inspecting various infrastructures in the province and city.

Below is a MAP OF ACTIVE FAULTS AND TRENCHES IN MINDANAO. You could see the EAST BOHOL FAULT in the map (which triggered the recent earthquake) just across the seas fronting the province of Misamis Oriental. In the map, the fault nearest to Cagayan de Oro is CABANGLASAN FAULT on the eastern part of the province.

In a more updated map, the nearest identified fault is TAGOLOAN RIVER FAULT- which is basically the Tagoloan River.

However, as shown in the SEISMICITY MAP below (1907-2001), less or not much earthquakes are triggered by the said faults. The bulk of earthquakes are generated in the eastern to southeastern part of Mindanao.

Still, let us not be complacent – as stated by PHIVOLCS Director Renato Solidum, in order for a structure to withstand an earthquake, there should be three factors to consider: design, material and workmanship.
