  1. LESSON 3: ACTIVE FAULT LINES IN THE PHILIPPINES

  2. The fault lines in the Philippines

  3. PHIVolcs- Philippine institute of volcanology and seismology • Marikina Fault Line – is the most geologically active fault line in the Philippines. • - it is located in East of Metro Manila and cuts through all the modern and progressive portions of Manila, Rizal, Marikina City, Quezon City such as Eastwood, Rockwell, Ortigas Center, Bonifacio Global City, Ayala Center, and Alabang. • - it was renamed to West Valley Fault.

  4. Director of Phivolcs • - Director Raymundo Punongbayan • Why is it he renamed the Marikina Valley Fault? • - because it caused panic to the residents of Marikina, as well as most of the business community within the inclusive areas.

  5. Seismologist- said that once the West Valley Fault Line moved, it can lead to the eruption of Taal volcano just what happened in June 1990 earthquake when the Central Philippine Fault moved. • THE CENTRAL PHILIPPINE FAULT ZONE • PFZ- PHILIPPINE FAULT ZONE • - is a transition zone with slow slip and creep activity.

  6. It comprises the Guinyangan Fault, Masbate Fault, and Central Luzon Fault. • This is found to be the site and sources of fault creep activity, slow slip event and great earthquakes in the archipelago. • Willis(1937) and Allen(1962) • - studied the PFZ. • - they said that PFZ is comparable to San Andreas Fault in California because on its geologic features, faulting and seismic characteristics.

  7. Ritcher Scale- designed by Dr. Charles F. Ritcher of the California Institute of Technolog. • - is the best known logarithmic scale in measuring the magnitude( strength of the shock waves) of earthquakes.

  8. Modified version of the ritcher scale

  9. Earthquake in the philippines • Pacific Ring of Fire • - where the philippines is located and it is a series of interconnected seismic plates that cause earthquakes and volcanic eruptions. • - the country sits on the Philippine plate, which is sandwiched by the Pacific Plate and Indian Plate.

  10. List of the most powerful earthquakes

  11. What are those examples of damages that caused by earthquakes? • Earthquakes pose hazards to humans. • The vibrations can cause the considerable shaking of the ground. • Tsunami in its English equivalent means “seismic sea waves”. • Thy can be caused by the following phenomena: The formation of an earthquake: What are they?

  12. What happen if the two oceanic plates meet and collide with one another? • What if the two colliding plates moved? • What is the energy released? • When the waves travels and enter shallower water in the coastal area. What will happened? • If the speed of the tsunami is diminished, but the wave height is increased drastically. What will be the cause?

  13. Answers: • The energy stored between them. • The denser plates subducts and the lighter plate is up thrusted. • The energy released is transferred to the water. • It begins to increase in heights and produces a series of rushing waves. • It can cause destruction of life and of property by floating debris and the impact of water.
