Seismometry - an overview ScienceDirect Topics
WebA seismometer is a very sensitive instrument that can detect movements of the Earth's surface. The surface is in constant motion due to natural and man-made phenomena. For example, the solid Earth tide is the stretching of the Earth due to the gravitational pull of the moon. Phoenix, Arizona slowly rises and falls twice a day about 40 cm due to ... Webthe motion of the sensing frame to its suspended proof mass. The proof mass in most broadband seismometers is a boom hinged at one end and balanced near a null point by a mainspring. A capacitive displacement transducer is often used to sense boom deflection.
