WebAnswer: The device is called a seismograph. It converts mechanical motion of the particles of the earth into electrical signals which after some processing drive a pen writing on a paper on a rotating drum or control the intensity of a spot of light moving over a photographic paper. These days, t... WebTypes of seismic waves: S-waves. Secondary waves or S-waves are seismic waves that travel at speeds of about 50% to 60% of the speed of the primary waves. Their effects are hence only felt after the effects of the P-waves during an earthquake. S-waves are also classified as body waves as they move along the inner layers of the Earth. magnolia arkansas chamber of commerce
