Scale to measure earthquakes
The Richter Scale measures earthquake strength from 0–10 and increases in powers of 10 between each number. So an earthquake registering 2 on the Richter scale is 10 times stronger than a quake registering 1. Subsequently, an earthquake registering at 3 on this scale is 10×10 times stronger than that measuring at 1 on this scale, and so on.In 1979, as geologists developed more accurate techniques for measuring energy release, a new scale replaced the Richter: the moment magnitude, or MW scale, which seeks to measure the energy released by the earthquake. It’s also a logarithmic scale and comparable to Richter for small and medium quakes—a 5.0 on the Richter scale, for example ...

The dashed lines represent the reference curve for the decrease in peak-motion amplitude with increasing distance from the earthquake. A magnitude 3.0 earthquake is defined as the size event that generates a maximum ground motion of 1 millimeter (mm) at 100 km distance. To complete the construction of the magnitude scale, Richter had to ...It is unusual for a year to go by without three or four earthquakes measuring 6.0 or more. Japan accounts for about 20 percent of the earthquakes of magnitude 6 or greater on the Richter scale. Each day about 1,000 tremors that can be felt are produced in Japan. More than 130,000 quakes were logged in Japan in 2005.The pH scale is a logarithmic scale used to measure acidity. The pH scale measures how basic or acidic a substance is, and it ranges from 0 to 14. On the pH scale, a pH of 7 is neutral, less than 7 is acidic and higher than 7 is basic.The intensity scale consists of a series of certain key responses such as people awakening, movement of furniture, damage to chimneys, and finally - total destruction. Although numerous intensity scales have been developed over the last several hundred years to evaluate the effects of earthquakes, the one currently used in the United States is the …What we can measure is the size of the trace on a seismograph (how big the wiggle is on those graphs of seismic activity).

In the United States, we use the modified Mercalli scale, which was adjusted to account for differences in buildings between Italy and southern California. Earthquake size, as measured by the Richter Scale is a well known, but not well understood, concept. The idea of a logarithmic earthquake magnitude scale was first developed by Charles Richter in the 1930's for measuring the size of earthquakes occurring in southern California using relatively high-frequency data from nearby …The moment magnitude scale is based on the total moment release of the earthquake. Moment is a product of the distance a fault moved and the force required to move it. It is derived from modeling recordings of the earthquake at multiple stations. Moment magnitude estimates are about the same as Richter magnitudes for small to large earthquakes. The Richter scale was originally designed to measure medium-sized earthquakes, those between magnitude 3 and 7, and within a distance of about 400 miles. The moment magnitude scale was created in 1979 to deal with these issues, but it builds on the Richter scale because it was already so accurate for small- to medium-sized quakes.
