An instrument that record duration of an earthquake
Correct Answer
Seismograph
Explanation
A seismograph is an instrument that is used to record the duration of an earthquake. It consists of a pendulum or a mass suspended from a frame, which remains stationary during an earthquake while the ground moves.
