Study Notes
Faults and Earthquakes
- A fault is a break in the Earth's crust where movement has taken place
- The Philippine Fault Zone is a 1200-km long fault that spans the Philippines from Luzon to Mindanao
- Frictional forces hold rocks in place and prevent movement
- Earthquakes occur when friction is overcome and the rocks suddenly slip along the fault
- The focus or hypocenter of an earthquake is the point underground where rocks initially move
- Seismic waves radiate outwards from the focus
- The epicenter is the point on the Earth's surface directly above the focus
- Surface waves, also known as L-waves, are the slowest and most destructive waves
Active and Inactive Faults
- Active faults are faults that have moved in the recent past and are likely to move again
- Inactive faults are faults that have not moved in recent geological time and may or may not move again
- It is important to identify active faults as they pose a significant risk of earthquakes
- Structures should not be built in areas prone to earthquake activity
Intensity and Magnitude
- Magnitude is the strength of an earthquake, measured by a seismograph
- Intensity is the perceived shaking at a given location
- Earthquakes can have the same magnitude but varying intensity depending on location
Preventing Destruction from Earthquakes
- Knowing the location of faults is crucial to prevent destruction from earthquakes
- Structures should not be built on active fault lines
- PHIVOLCS has mapped out the fault lines in the Philippines
