Answer:Seismometers. I hope this helps you understand.
Step-by-step explanation:
Seismometers are instruments that sense earthquake waves and transmit them to a recording device.
The instruments that sense earthquake waves are called seismometers. They are used to detect ground motion during an earthquake. When an earthquake occurs, the ground shakes and the seismometer detects this motion. The data is then transmitted to a recording device, where it can be analyzed to determine the characteristics of the earthquake. Seismometers work by measuring the acceleration of the ground in three directions. They can detect both the primary waves (P-waves) and the secondary waves (S-waves) that occur during an earthquake. P-waves are the fastest and arrive first, while S-waves are slower and arrive later. By analyzing the data from seismometers, seismologists can determine the location, magnitude, and other characteristics of the earthquake.
Seismometers are devices that are used to detect and measure vibrations or movements in the Earth’s surface, caused by seismic waves generated by earthquakes, volcanic activity, or other geological events. Seismometers work by measuring the movement of an internal mass, such as a pendulum, in response to the vibrations caused by seismic waves. These measurements can be used to determine the magnitude, location, and other characteristics of seismic events.
