Ninety-percent of Cavite will be affected in case a 7.2 magnitude earthquake hits the province.
“I don’t want my statement to be too alarming, but 90 percent of the province will be largely affected if 7.2 magnitude of [an]earthquake hits Cavite,” Ronnie Trinidad, the head of Operations of the Provincial Disaster Risk and Reduction Management Council for Cavite, told The Manila Times.
Trinidad has been working in disaster and rescue management since 2007 and has under him 160 people who are well-trained in rescue operations. There are also hundred of rescue volunteers in Cavite.
The Philippine Institute of Volcanology and Seismology recently released the Valley Fault System Atlas, which are large-scale maps showing areas that are near an earthquake fault. It identified the West Valley Fault that could possibly generate a magnitude 7.2 earthquake, while the East Valley Fault could generate a magnitude 6.2 earthquake.
The West Valley Fault can directly affect the following localities in Cavite: Carmona; General Mariano Alvares; and Silang. Meanwhile, the following will not be directly affected by that fault line: Ternate; Maragondon; and Magallanes.
Trinidad said Cavite has 3.8 million people and a powerful “earthquake can hit at anytime, it will be disastrous if powerful earthquake hits the province,” in terms of damages in infrastructure and buildings. He did not discount human casualties.
There have been two strong earthquakes in the Philippines since 1976. On August 16, 1976, the Moro Gulf Earthquake hit the southern part of Mindanao and killed between 5,000 and 8,000 people. It had magnitude of 8.0.
And on July 16,1990, the Luzon Earthquake with magnitude of 7.9 hit parts of Northern Luzon which resulted to 1,621 deaths. Cabanatuan City and Baguio City incurred the highest numbers of casualties.
