A seismograph records earthquake waves.the correct answer is a seismometer a seismograph is the graph to show the recordings
A seismometer / seismograph.A seismograph measures and records the waves generated by earthquakes and similar seismic events.
Scientists use a recording instrument called a seismograph to detect ground motions caused by seismic waves from earthquakes.
A seismogram traces the earthquakes motion that is created by the seismograph and the seismograph records vibrations in the ground and determines the location and strength of an earthquake.
A Chinese scientist named Chang Heng invented a machine called Dragon Jar that was used to measure earthquakes.

A seismometer.
Science records about 14,000 earthquakes in and around New Zealand each year. Most are small, but between 100 and 150 are big enough to be felt. The Institute records these earthquakes on a nationwide network of instruments called seismographs. New Zealand's position on the boundary of the Australian and Pacific plates is the reason for the large number of earthquakes.

A seismograph is a tool scientist uses to measure earthquakes.
earthquakes that immediately follow a major earthquake are called "aftershocks" as to small earthquakes before large earthquakes are called "foreshocks".
