Bookmark or Share- Earthquake Magnitude, Energy Release, and Shaking IntensityMagnitude is the size of the earthquake. An earthquake has a single magnitude. The shaking that it causes has many values that vary from place to place based on distance, type of surface material, and other factors. See the Intensity section below for more details on shaking intensity measurements. Types of Magnitudes.
- Earthquake Magnitude - IllinoisThere are two important things to remember about earthquake magnitude: The size of an earthquake increases by a factor of 10 as magnitude increases by one whole number. A magnitude 6.0 earthquake, then, is 10 times larger than a 5.0; a magnitude 7.0 is 100 times larger, and a magnitude 8.0 is 1,000 times larger than a 5.0.
- 7.0 magnitude earthquake strikes California | AP NewsSAN FRANCISCO (AP) — A 7.0 magnitude earthquake shook a large area of Northern California on Thursday, knocking items off grocery store shelves, sending children scrambling under desks and prompting a brief tsunami warning for 5.3 million people along the U.S. West Coast.
- Moment magnitude, Richter scale - what are the different magnitude ...Magnitude scales, like the moment magnitude, measure the size of the earthquake at its source. An earthquake has one magnitude. The magnitude does not depend on where the measurement is made. Often, several slightly different magnitudes are reported for an earthquake.
- Richter Scale and Earthquake Magnitude - Science Notes and ProjectsThe Richter magnitude for the 1906 San Francisco earthquake was approximately 7.9. So, the magnitudes are fairly close for this particular earthquake. However, for very large earthquakes, the Richter scale underestimates the energy release, while the moment magnitude scale remains accurate.
