How to survive a tsunami

ONCE an earthquake occurs, the next thing that the public should prepare for is the possible tsunami.

In a leaflet from the Philippine Institute Volcanology and Seismology (Phivolcs), tsunami is described as a series of waves commonly generated by undersea earthquakes.

Tsunami can occur if a quake is shallow (between 0 and 70 kilometers deep) and strong enough to displace parts of the seabed and disturb the mass of water over it. Tsunami wave heights could be greater than five meters.

Tsunami moves so fast, travelling at speeds up to 800 kilometers per hour across the ocean, according to the United States Geological Survey.

Will a tsunami strike Manila and other nearby provinces if a 7.2-magnitude earthquake occurs?

Phivolcs geologist Jeffrey Perez assured the public that the West Valley Fault, which traverses Manila, Bulacan, Laguna, Rizal and Cavite, is not capable of generating a tsunami unless the tremor is due to the movement of the Manila Trench.

In case of an undersea earthquake, Perez said residents along coastal areas in Manila and Camanava (Caloocan-Malabon-Navotas-Valenzuela) will be affected.
