THE Philippine Institute of Volcanology and Seismology (Phivolcs) has urged the public to
strengthen their structures and comply with the National Building Code of the Philippines.
The call was made after a 4.1 magnitude earthquake struck seven kilometers northwest of Leyte town in Leyte on Tuesday, March 3, 2020.
The tremor came a day after a magnitude 5.5 earthquake hit some parts of the Visayas at 5:20 a.m. on Monday, March 2.
According to Robinson Jorgio, Phivolcs Cebu officer-in-charge, the quake was due to the recent activity of the Philippine Fault Line.
“The Philippine Fault already has a lot of activity for the past years, since 2017, and it is a very long fault,”
He added that every fault has its own “Big One” or a feared powerful earthquake that is why everyone should always be prepared especially that earthquakes can’t be
“Every fault has its own the ‘Big One.’ It would be hard because we can’t predict earthquakes, that is why we released a statement that structures should be built strong,” said Jorgio.
The 4.1 magnitude earthquake last March 3 was felt in the following areas:
Intensity 4 - Naval, Biliran;
Intensity 2 - Tanauan, Barugo, Palo, Jaro, Tolosa, Dagami, San Miguel, Dulag, Babatngon, Leyte; Tacloban City
Instrumental Intensity 4 - Ormoc City; Naval, Biliran
Instrumental Intensity 3 - Palo, Leyte; Borongan City
Jorgio said that in Cebu City, those who were in higher areas felt the quake at Intensity 1. However, those on the ground may not have felt the tremor at all.
“Magnitude is different from intensity, so those who were on the ground may not have felt the quake while those in higher buildings probably felt it,” he added.
