Introduction

The Philippines is located along the Pacific Ring of Fire, making it prone to earthquakes and volcanic eruptions. In fact, the country experiences an average of 20 earthquakes every day, most of which are too weak to be felt. However, there are some areas in the Philippines that are more susceptible to earthquakes than others, and the National Capital Region (NCR) is one of them.

What is a Fault Line?

A fault line is a fracture or break in the Earth’s crust where two tectonic plates meet. When these plates move against each other, it can cause an earthquake. In the Philippines, there are several fault lines, including the West Valley Fault and the Manila Trench, which are both located in the NCR.

The West Valley Fault

The West Valley Fault is a 100-kilometer-long fault line that runs through six cities in the NCR, namely Quezon City, Marikina, Pasig, Makati, Taguig, and Muntinlupa. It is capable of producing a magnitude 7.2 earthquake, which can cause widespread destruction and loss of life.

The Manila Trench

The Manila Trench is a subduction zone located off the coast of Luzon, which is capable of generating a magnitude 7.9 earthquake. While it is not directly under the NCR, it can still cause significant damage to the region.

What to Do Before an Earthquake?

It is important to be prepared before an earthquake strikes. Here are some things you can do to minimize the risk of injury or damage to your property:

• Create an emergency kit that includes food, water, first aid supplies, and other essentials.
• Identify the safe spots in your home or workplace, such as under a sturdy table or desk.
• Secure heavy furniture and appliances to prevent them from falling or tipping over.
• Practice earthquake drills with your family or colleagues.

What to Do During an Earthquake?

If you are indoors when an earthquake strikes, follow these safety tips:

• Drop to the ground and take cover under a sturdy table or desk.
• Hold on to the table or desk and protect your head and neck.
• Stay away from windows, mirrors, and other glass objects.
• If you are in bed, stay there and cover your head with a pillow.

What to Do After an Earthquake?

After the earthquake, check yourself and your family for injuries. If you are safe, check your home or workplace for damage. If you smell gas or see sparks, turn off the gas and electricity immediately and evacuate the building. Do not use matches or lighters, as gas leaks can cause explosions.

Conclusion

Knowing about the fault lines in the Philippines, particularly in the NCR, is crucial in preparing for earthquakes. By being aware of the risks and taking the necessary precautions, you can protect yourself, your family, and your property from the devastating effects of earthquakes.
