Moment Magnitude Scale

The Moment Magnitude Scale (Mw) is a way scientists measure the size of earthquakes. It quantifies the energy released when the Earth's crust shifts during a quake. Unlike older scales, it provides a consistent measurement for very small and very large earthquakes by analyzing factors like the area that slipped, the amount of movement, and the strength of the rocks involved. This helps compare earthquakes accurately worldwide. Essentially, Mw offers a reliable, scientific way to understand the true size of an earthquake, regardless of where or how big it is.
