Seismometers. For information on how seismometers are used, please see the related question.
A seismometer (replacing the outdated term seismograph), but other instruments may also respond to an earthquake. The simplest example of a seismograph is a pendulum.
A seismometer is used to detect and record earthquakes by measuring the motion of the ground. It consists of a mass suspended on a spring that moves with the vibrations caused by an earthquake, which is then recorded on a seismograph.
A seismograph is an instrument used for recording the intensity and duration of an earthquake/tremor.This device is not only used for earthquakes but also for other seismic events. For example monitoring the vibrations produced during construction work and during blasting in the mining and quarrying industries.The seismograph was invented by John Milne who was an English seismologist and geologist.
The seismograph was invented during the Han Dynasty in ancient China. Specifically, it was created around 132 AD by the polymath Zhang Heng. This early seismograph, known as the "Houfeng Didong Yi," was designed to detect and indicate the direction of earthquakes. It marked a significant advancement in the understanding of seismic activity in ancient times.

The seismograph was important to China because it was the first instrument capable of detecting and measuring earthquakes. It helped the Chinese government develop early warning systems for earthquakes, which saved lives and enabled better disaster preparedness. Additionally, it contributed to the advancement of seismology as a scientific field in China.
the first seismograph had about 8 dragons on the outside of the egg shaped pot. the dragons had balls in their mouth that were pure metal. if theground shook, the ball would drop from the mouth, and go into a metal frog shaped cup.
A seismograph is used to measure ground movement or vibrations on the Richter scale.
