The largest earthquake ever recorded was a magnitude 9.5 on May 22, 1960 in Chile on a fault that is almost 1,000 miles long…a “megaquake” in its own right.

The size of the earthquake is called its magnitude. There is one magnitude for each earthquake. There is one magnitude for each earthquake. Scientists also talk about the intensity of shaking from an earthquake, and this varies depending on where you are during the earthquake.Defining Earthquake Magnitude – Types of Scales · Richter Scale · Earthquakes Larger Than 7.0 – Moment Magnitude Scale · Defining Earthquake Intensity – Modified ...From 1935 until 1970, the earthquake magnitude scale was the Richter scale, a mathematical formula invented by Caltech seismologist Charles Richter to compare quake sizes. The Richter Scale was replaced because it worked largely for earthquakes in Southern California, and only those occurring within about 370 miles of seismometers.

The most popular scale of energy evaluation in earthquakes is the local scale of the Richter magnitude. Thus, the increase is a degree of magnitude of the 32-fold increase in the released seismic energy. An earthquake of magnitude 2 is subtle until the magnitude 7 is the lower limit of destructive earthquakes that cover large areas.Over the last decade, the AZGS has improved seismic monitoring throughout the state and we are now capable of detecting in-state earthquakes with a Magnitude 3.0 or larger. Most of the earthquake activity is located within 5-10 miles of known faults.

Twenty minutes after the main earthquake, a magnitude 4.9 aftershock hit the region.An earthquake is caused by a sudden slip on a fault. The tectonic plates are always slowly moving, but they get stuck at their edges due to friction. When the stress on the edge overcomes the friction, there is an earthquake that releases energy in waves that travel through the earth's crust and cause the shaking that we feel.
