WebMaking Sense of the Modified Mercalli Intensity Scale (MMI) –A Measure of Shaking The Modified Mercalli Intensity (MMI) estimates the shaking intensity from an earthquake at a specific location by considering its effects on people, objects, and buildings. At high intensities (above MMI 6), earthquake shaking damages buildings. The severity of the WebThe moment magnitude scale is based on the total moment release of the earthquake. Moment is a product of the distance a fault moved and the force required to move it. It is derived from modeling recordings of the earthquake at multiple stations. Moment magnitude estimates are about the same as Richter magnitudes for small to large earthquakes.

Can "MegaQuakes" really happen? Like a magnitude 10 or larger?

WebNo, earthquakes of magnitude 10 or larger cannot happen. The magnitude of an earthquake is related to the length of the fault on which it occurs. That is, the longer the … WebAn earthquake's intensity is determined by observing its effects at a particular place on the Earth's surface. Intensity depends on the earthquake's magnitude, the distance from the epicenter, and local geology. These scales are based on reports of people awakening, felt movements, sounds, and visible effects on structures and landscapes.
