Study Notes
The Richter Scale
- The Richter scale was invented by Charles Richter.
- The Richter scale measures the magnitude of an earthquake, which is the amount of energy released during the earthquake.
- The Richter scale was originally focused for use in Southern California.
Charles Richter's Background
- Before his involvement in seismology, Charles Richter studied astronomy and physics.
How the Richter Scale Works
- The Richter scale measures the amplitude of the seismic waves recorded by a seismograph.
- The Richter scale ranges from 0 to 10, with higher numbers indicating more powerful earthquakes.
- The main limitation of the Richter scale is that it becomes less accurate for higher magnitude earthquakes, as it saturates at around 7.0.
Earthquake Intensity
- With each unit increase in Richter scale magnitude, the intensity of ground shaking increases by a factor of 10.
- The intensity of ground shaking also increases with decreasing distance from the epicenter.
The Moment Magnitude Scale
- The Moment Magnitude Scale is designed to measure the size of an earthquake based on the size of the rupture area, the average amount of slip on the fault, and the amount of energy released during the earthquake.
- The Moment Magnitude Scale determines the overall magnitude of an earthquake by considering the moment of the earthquake, which is a measure of the size of the rupture area and the amount of slip on the fault.
