Seismic magnitude scales are used to describe the overall strength or "size" of an earthquake. These are distinguished from seismic intensity scales that categorize the intensity or severity of ground shaking (quaking) caused by an earthquake at a given location.Charles F. Richter devised his magnitude scale in the mid-1930s while investigating earthquakes in California. He used seismographs which magnified ground motion 2800 times, and as a baseline, he defined a magnitude 0 earthquake as being one that would produce a record with an amplitude of one-thousandth of a millimeter at a distance of 100 ... Earthquake Intensity - Modified Mercalli Intensity (MMI) Scale.

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 seismograph stations. The Richter scale does not have an upper limit. The Richter scale is a logarithmic representation of the amount of energy released by an earthquake, or its magnitude. As of 2014, the earthquake that rated highest in recorded history was a 9...scales. For large earthquakes the Richter as well as body wave magnitude scales saturate. No matter how large the earthquake is, the magnitude computed from body waves tend not to get much above 6.0 to 6.5. The surface-wave scale is less affected by this problem, but for very large earthquakes M>8 the surface-wave scale also gets saturated.Whether you’re an accomplished chef or a beginning home cook, a reliable kitchen scale can make all the difference when you’re cooking your favorite recipes.

The Richter Scale. 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 ...The main earthquake was preceded by a number of large foreshocks, with hundreds of aftershocks reported. One of the first major foreshocks was a 7.2 M w event on 9 March, approximately 40 km (25 mi) from the epicenter of the 11 March earthquake, with another three on the same day in excess of 6.0 M w. The Global Earthquake Model (GEM) Global Seismic Hazard Map (version 2023.1) depicts the geographic distribution of the Peak Ground Acceleration (PGA) with a 10% probability of being exceeded in 50 years, computed for reference rock conditions (shear wave velocity, Vs30, of 760-800 m/s).List of earthquakes in 2018 This is a list of earthquakes in 2018.
