An ocean-bottom
seismometer (OBS) is a
seismometer that is designed to record the earth motion under oceans and lakes from man-made

seismometer s. The moment magnitude is the most common scale on which earthquakes larger

seismometer , which discerned the cardinal direction of an earthquake
Kaynak: Zhang HengThe primary purpose of a
seismometer is to locate the initiating points of earthquake epicenter s. The secondary purpose, of determining

seismometer s.
