They use the Richter scale to measure magnitude and Moment Measure to measure energy released.
The rating system that estimates the total energy released by an earthquake is called the moment magnitude scale (Mw).
Earthquake magnitudes are rated using the moment magnitude scale. Moderate and small earthquakes (those with a magnitude below 7) are also measured using the Richter scale. Please see the related question for more information.
The strongest earthquake ever recorded occurred in Chile on May 22, 1960. This earthquake had a magnitude of 9.5 on the Richter scale.
No. The scale you are describing is an intensity scale such as the modified Mercalli scale. The Richter scale is in fact a magnitude scale which describes the amount of energy released by an earthquake.
An earthquake alarm typically consists of a sensor that detects seismic activity, a processor to analyze the data and determine if it is an earthquake, and an alarm system to alert people of the impending earthquake. When the sensor detects shaking characteristic of an earthquake, the processor triggers the alarm system to sound an alert, giving people time to take cover or evacuate. It is designed to provide early warning to minimize potential damage and protect lives.
Geologists use the Moment Magnitude Scale, a rating system that estimates the total energy released by an earthquake. The Moment Magnitude Scale can be used to rate earthquakes of all sizes, near or small.-Source is from Prentice Hall: Science Explorer Earth Science textbook page 158 Ch. 5: Earthquakes

The rating system developed by Charles Richter in 1935 is called the Richter magnitude scale. It is used to measure the strength or magnitude of earthquakes based on the seismic waves they produce. The scale is logarithmic, meaning each whole number increase represents a tenfold increase in amplitude and approximately 31.6 times more energy released.
No it is based on a scale of 1 to 10 and the only way a 10.0 earthquake could happen would be all of the faults join together to form one big earthquake.
These are known as magnitude scales.The Moment magnitude scale (abbreviated as MMS; denoted as MW) is used by seismologists to measure the size of earthquakes in terms of the energy released.The US Geological Survey assigns MMS figures to most earthquakes, but news reports may still refer to the Richter scale, the familiar earlier scale that was superseded by the MMS.
The moment magnitude scale is more accurate and reliable for measuring large earthquakes because it takes into account the amount of energy released by the seismic event. It provides a more consistent measure across different types of earthquakes compared to other magnitude scales. Additionally, moment magnitude can better estimate the potential for ground shaking and damage.
