MANILA, Philippines – A magnitude 6.3 earthquake jolted Batangas on Friday, August 11, according to the Philippine Institute of Volcanology and Seismology (Phivolcs).

Phivolcs said aftershocks are expected after the quake, which was tectonic in origin, hit Nasugbu, Batangas, at 1:28 pm Friday.

Here are 3 things to do during aftershocks according to Phivolcs Director Renato Solidum.

Stay alert and avoid areas vulnerable to landslides

“People are reminded to be cautious of stuctures with signs of damage and cracks as this may be further damaged by aftershocks,” Solidum said. 

The Phivolcs director added that slopes in affected areas should be checked for tension cracks that may have resulted from the intense shaking. Consequently, residents are advised to avoid areas that are susceptible to landslides. 

Do not enter heavily-damaged structures

People are advised against entering heavily damaged structures or houses. 

“In cases of houses and buildings with damages, it is best to contact the municipal engineering offices for advice,” Solidum said. 

Municipal engineers are expected to recommend appropriate action to strengthen the structural integrity of the damaged buildings and houses.  (READ: What makes houses earthquake-ready?)
