LAOAG CITY — A magnitude 5 earthquake hit Dalupiri Island in Calayan, Cagayan on Friday morning, according to the Philippine Institute of Volcanology and Seismology (Phivolcs).
The earthquake, which was tectonic in origin, occurred at 10:45 a.m. with a depth of 31 kilometers.
Intensity I was felt in Pasuquin, Ilocos Norte, while instrumental Intensities IV and I were recorded in Calayan, Cagayan and Pasuquin, Ilocos Norte.
Reported intensity is the traditional way of knowing the intensity based on reports by people who felt the earthquake.
Instrumental intensity, on the other hand, is measured using the intensity meter that measures ground acceleration.
There are no expected damage from the earthquake, but aftershocks are likely, Phivolcs said.
