A seismograph is an instrument that records the shaking of the earth's surface caused by seismic waves and determine the location of an epicenter. Seismic phenomena are generally explained as the result of interactions and other processes at or near the edges of a few large mobile plates of lithosphere that spread apart at the ocean ridges where new surficial materials arise, slide past one another along the large strike-slip faults, and converge at the island . They only travel through solid material, and so are stopped at the liquid layer in the Earths core. sikringbp and 28 more users found this answer helpful. seismograph merely registers an earthquake.

Why do scientists need three seismographs? Answer: Seismic monitoring. Direct investigation involves the use of rock samples directly to study the interior. In seismology, Love waves (also known as Q waves (Quer: German for lateral)) are surface seismic waves that cause horizontal shifting of the Earth during an earthquake.
