How are earthquakes measured today
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 … WebA seismometer operates on the same concept as a free-falling heavy object coupled to a frame anchored to the ground—the seismometer's frame shifts in the same way as the Earth does in response to earthquake vibrations. The inertia of the heavy mass within the frame keeps it from moving. The relative movement of the structure and the group ...
