D
the location of the epicenter
Explanation: 

Detailed explanation-1: -How does a Seismograph record earthquake data? As the seismograph shakes under the mass, the recording device on the mass records the relative motion between itself and the rest of the instrument, thus recording the ground motion.

Detailed explanation-2: -A seismogram is a record of the ground motions caused by seismic waves from an earthquake. A seismograph or seismometer is the measuring instrument that creates the seismogram.

Detailed explanation-3: -Seismographs. During an earthquake, vibrations caused by the breakage of rock along a fault zone radiate outward from the point of rupture. The instrument used to record and measure these vibrations is called a seismograph.

Detailed explanation-4: -A record produced by a seismograph on a display screen or paper printout is called a seismogram.

Detailed explanation-5: -A seismograph is a machine which measures an earthquake.
