Let’s help protect ourselves for the major earthquake that is just around the corner.
The Philippine Institute of Volcanology and Seismology (PHIVOLCS) of the Department of Science and Technology (DOST) has a checklist for earthquake safety entitled “How Safe is My House?: Self-check for Earthquake Safety of Concrete Hollow Block (CHB) Houses in the Philippines”.
Some important notes include:
- there were earthquake-resistant building standards set in 1992 implying that structures built before then need evaluation by a civil engineer;
- cement hollow blocks (CHB) standard size is 6”;
- diameter steel bars standard size is 10mm;
- diameter steel bars should be spaced 40cm apart side to side and connected to steel bars laid every 3 layers of CHB;
- walls should not be wider than 3 meters without perpendicular walls/supports;
- regular house maintenance/repair should be conducted to prevent deterioration.
In the interest of accuracy, we are posting the entire “House self-check” material. There are 12 questions posed to residents which serve as guidelines as to what may be a cause for concern, close examination by an engineer or outright repair.
