Magnitude and Intensity measure different characteristics of earthquakes. Magnitude measures the energy released at the source of the earthquake. Magnitude is determined from measurements on seismographs. Intensity measures the strength of shaking produced by the earthquake at a certain location.The magnitude of frictional force is equal to the magnitude of the normal force multiplied by a frictional coefficient. The normal force is proportional to the force of gravity and is the ground pushing back up against an object.The Richter Magnitude Scale is the method of earthquake measurement widely used in the United States last century. Richter's idea was to track the amount of energy released by a quake the way an ...The 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. The Bortle Scale and NELM (naked-eye limiting magnitude) are closely related. NELM represents the faintest star(s) that your naked eye can see in the conditions being measured.
