Study Notes
Earthquake Intensity
- Measures the degree of shaking at a specific location based on damage.
Earthquake Magnitude
- An estimate of the total energy released during an earthquake based on seismic records.
Geological Phenomena
- Refers to a range of ground movements like rockfalls, slope failures, and debris flows.
Can Earthquakes be Predicted?
- Currently, there is no reliable method to predict earthquakes.
Seismic Waves
- Waves of energy that travel through the Earth's interior and along its surface.
Long Waves (L-Waves)
- Travel along the Earth's outer layer and are responsible for surface damage.
- They have longer periods than other seismic waves.
Elastic Rebound Theory
- Describes how stored energy in rock masses is released during earthquakes.
- Rock masses under stress eventually reach their breaking point and rupture, releasing energy as earthquake waves.
Impact of Earthquakes
- Earthquakes are one of the most destructive natural forces on Earth.
- They cause significant damage to buildings, infrastructure, and can lead to fires and loss of life.
- Earthquake damage can be measured and assessed.
