A seismometer or seismograph.
Please see the related question for information on how seismologists use them to find the epicentre of an earthquake.
Also please see the related link for more information on seismometers.
There are two instruments, which are basically the same thing. There is the seismograph , and a more specific tool measures the waves on what is called the Richter scale. Earthquakes are given a number from one to ten, ten being the strongest. The strongest earthquake that their ever was, was measured a 9.3.
A seismometer can be used to measure the magnitude of an earthquake.
Seismograph is another Greek term from Seism - "the shakes" and Graphos - "I draw". It is often used for seismometer, though it is more applicable to the older instruments in which the measuring and recording of ground motion were combined than to modern systems, in which these functions are separated. Both types provide a continuous record of ground motion; this distinguishes them from seismoscopes, which merely indicate that motion has occurred, perhaps with some simple measure of how large it was

The Moment Magnitude scale measures earthquake intensity using seismometers.
A seismometer (the old fashioned term was seismograph).
Earthquake magnitude is reported using the Moment magnitude scale which has now replaced the Richter or Local magnitude scale.
The seismometer measures it, and the seismograph records it.
a tool used by scientists to measure earthquakes by movement
Yes, a seismograph is a type of technology used to detect and record earthquakes. It measures the motion of the ground caused by seismic waves generated by earthquakes or other sources of seismic energy.
Seismometers are instruments that record earthquakes by detecting the vibrations in the Earth's crust. These devices can measure the magnitude and location of an earthquake by tracking the seismic waves that are generated during the event.
A seismometer is an instrument used to measure earthquakes by detecting and recording ground motions. It consists of a sensor that responds to ground movements, which are then converted into electrical signals that can be recorded and analyzed.
A seismograph records earthquake waves.the correct answer is a seismometer a seismograph is the graph to show the recordings

Seismometer (or seismograph) and it measure seismic waves
The strainmeter, by which its seismometer component detects the vibrations or shock waves that its seismograph records, is the scientific instrument that's used to predict and measure earthquakes.

seismograph is one instrument that could measure earthquakes and volcanoes etc but seismograph is many times use at earthquake!
