How did Zhang Heng seismograph work?

Ancient Chinese Seismometer Used Dragons and Toads. In 132 AD, Chinese astronomer Zhang Heng created a seismometer, a device that detects the ground's movement during an earthquake. It couldn't predict quakes but it did show what direction they were coming from — even when they were hundreds of miles away!

How does a seismograph work?

A seismograph is the device that scientists use to measure earthquakes. The goal of a seismograph is to accurately record the motion of the ground during a quake. Therefore, most seismographs involve a large mass of some sort. You could make a very simple seismograph by hanging a large weight from a rope over a table.

How does a seismograph detect and record seismic waves?

A seismograph, or seismometer, is an instrument used to detect and record seismic waves. Seismic waves are propagating vibrations that carry energy from the source of an earthquake outward in all directions. They travel through the interior of the Earth and can be measured with sensitive detectors called seismographs.
