A seismometer is a seismograph made to measure the direction, intensity, and duration of earthquakes. It does this by measuring the actual movement of the ground.
The Modified Mercalli Intensity (MMI) Scale rates earthquakes acxcording to how much damage they cause at a particular place and the measured ground accelarattions as recorded by a seismomter. In Europe the Macroseismic sclae is used which is similar in concept to the MMI scale.
