Earthquake magnitude serves as a crucial measure of the energy unleashed during seismic events. Traditionally quantified using the Richter scale, developed in the 1930s, or the moment magnitude scale (Mw), it reflects the intensity of seismic waves at the earthquake's epicenter. Unlike Richter's scale, which assigns a single number, Mw considers the seismic moment, offering a more comprehensive assessment of an earthquake's true size and energy release. Each whole number increment on these scales signifies a tenfold rise in wave amplitude and roughly 31.6 times more energy. This understanding aids seismologists in assessing earthquake impact potentials, guiding strategies for mitigating hazards and safeguarding communities and infrastructure worldwide.
