Web11.3 Measuring Earthquakes. There are two main ways to measure earthquakes. The first of these is an estimate of the energy released, and the value is referred to as magnitude. This is the number that is typically used by the press when a big earthquake happens. It is often referred to as “Richter magnitude,” but that is a misnomer, and it ... Rayleigh waves are a type of surface acoustic wave that travel along the surface of solids.
