The 'Big One' Earthquake in the Philippines: Predictions, Preparations, and the San Andrea, Exercises of Reinforced Concrete Design

The impending 'big one' earthquake in the philippines, which is expected to have a magnitude of 7.2 or higher. It highlights the potential destruction, the efforts to locate safe open spaces, and the tectonic plates and fault system involved. The san andreas fault system is also explained as a point of comparison.

THE BIG ONE

“PHILIPPINES VERSION”

Submitted by: Acopiado, Ruben, B.

The Philippine Institute of Volcanology and Seismology (Phivolcs) has warned of a magnitude 7.2 (or possibly higher) earthquake called the ‘Big One’ that is bound to hit the country. When? They can’t exactly predict. The 6.1 quake last april 22,2019 that originated in Zambales and was felt throughout Luzon produced a lot of terrifying videos and posts on social media. The more recent 6.6- magnitude quake that in Cotabato on October 29 , 2019 look the lives of people, and was followed by a 6.5 earthquake two days later. If earthquakes of those magnitudes had the power to destroy establishments and make skyscrapers sickeningly sway, what more a 7.2-magnitude earthquake?

  • Because the West Valley Fault (WVF) runs through six cities in Metro Manila and adjoining provinces, the National Mapping and Resource Information Agency (NAMRIA) has already discovered and mapped SOSs in Metro Manila and has begun to do so for neighboring locations. In the Philippine Institute of Volcanology and Seismology's scenario, a tsunami is also expected (Phivolcs).

THE BIG ONE

Tectonic plates & fault system

Water distribution pipes will break, electric cables will be cut, and explosions will lead to fires everywhere. Communication will become difficult and this becomes a problem as people can’t call for help to put out fires or save them underneath all the rubble. Hospitals will also have a hard time responding to the thousands of victims asking for help. In other words, the picture being painted here is one of chaos.

  • The San Andreas Fault is the

transform (strike-slip) border

between two major plates of the

Earth's crust: the Northern Pacific to

the south and west and the North

American to the north and east,

according to plate tectonic theory.
