Study Notes
S Waves
- S waves move side to side and travel through solids only.
- They arrive after P waves during an earthquake.
Earthquake Epicenter
- The epicenter is located at the Earth's surface.
- It is the region directly above the earthquake's focus.
Fault Stress
- When stress accumulates at faults, energy may be released.
- Rocks can bend and break due to accumulated forces affecting them.
- These processes influence the behavior of Earth's rocks.
Richter Scale
- The Richter scale measures fault movement during earthquakes.
- It increases in magnitude with the amount of damage caused.
- The scale determines an earthquake's magnitude based on the size of its seismic waves.
Surface Waves
- Surface waves travel slower than P waves.
- They result in significant ground motion.
- These waves are produced by the interaction of P and S waves.
Earthquake Formation Factors
- Earthquakes are caused by moving tectonic plates.
- Rocks can break during stress, contributing to seismic activity.
- Movement occurring below the Earth's surface plays a crucial role in formation.
Seismographs
- Seismographs feature a curved graphing surface and are essential for locating epicenters.
- They utilize a needle on graph paper to measure seismic wave activity.
- Seismographs help determine the arrival times of P waves.
Geologists and Seismographs
- Geologists use global data from seismographs to analyze earthquakes and improve understanding.
Mercalli Scale
- The Mercalli scale evaluates earthquakes based on the damage caused.
- It employs Roman numerals to categorize the level of damage.
Comparison of S and P Waves
- Both S waves and P waves induce ground shaking.
- They travel through solids; P waves can also move through liquids.
- Both types of waves can transform into surface waves.
