# Earthquake California Richter Scale

Richter magnitude scale - Richter magnitudes. The Richter magnitude of an earthquake is determined from the logarithm of the amplitude of waves recorded by seismographs (adjustments are included to compensate for the variation in the distance between the various seismographs and the epicenter of the earthquake).

Richter scale The Richter magnitude scale was developed in 1935 by Charles F. Richter of the California Institute of Technology as a mathematical device to compare the size of earthquakes. The magnitude of an earthquake is determined from the logarithm of the amplitude of waves recorded by seismographs.

The Richter size scale (regularly abbreviated to Richter scale) is the most well-known standard of estimation for quakes. It was created in 1935 by Charles F. Richter of the California Institute of Technology as a scientific gadget to analyze the span of tremors.

The Richter Scale. Although similar seismographs had existed since the 1890's, it was only in 1935 that Charles F. Richter, a seismologist at the California Institute of Technology, introduced the concept of earthquake magnitude.

Three earthquakes hit California on Thursday, one as far south as Trabuco Canyon and a second all the way up to a spot off the coast of Eureka, according to the U.S. Geological Survey (USGS). A third earthquake struck near Lytle Creek, California, registering a 2.5 on the Richter scale. Trabuco ...

Scientists no longer rely on the the Richter scale to measure an earthquake's power. Here's how earthquakes are measured, and why a 7.1 quake is worse than you might imagine.

Richter Scale. What is the Richter Scale. The Richter magnitude scale (often shortened to Richter scale) is the most common standard of measurement for earthquakes. It was invented in 1935 by Charles F. Richter of the California Institute of Technology as a mathematical device to compare the size of earthquakes.
