  • A.seismogram
  • B.seismometer
  • C.isoseismal
  • D.accelerogram of intensity

Answer: A

Correct answer: seismogram

The seismogram is the record - formerly a trace on smoked paper or photographic film, now a digital time series. The seismometer is the sensor and the seismograph the complete instrument. An isoseismal is a contour of equal intensity on a map, which is a quite different product derived from observed effects rather than from an instrument.
