A magnitude 5.4 earthquake that is tectonic in origin shook Zamboanga del Norte on Thursday, the Philippine Institute of Volcanology and Seismology (Phivolcs) said.
The quake, which Phivolcs initially reported as magnitude 6.1, struck five kilometers southeast of Siocon at 11:41 a.m.
It was 43 kilometers deep.
Reported intensity is the traditional way of knowing the intensity based on reports of people who felt the earthquake.
On the other hand, instrumental intensity is measured using an intensity meter that measures ground acceleration. | GB with PNA reports
