The Philippine Institute of Volcanology and Seismology (PHIVOLCS) on Wednesday identified the fault that caused the 6.9-magnitude earthquake in Bogo City, Cebu on Tuesday, that left 63 people dead.In a press conference,

Surprisingly, they found that only around 10% of a quake’s energy causes the physical shaking most people associate with earthquakes. Overall, anywhere between 68 and 98% of the energy goes into generating heat around a quake’s epicenter. Less than 1% of that energy is used to break up rock and create new surfaces.

A powerful 6.9 magnitude earthquake struck off the central Philippines on Tuesday evening, causing damage to buildings and roads, and widespread power outages. While no casualties were immediately reported,
