The Full Story
The first device to detect earthquakes is traditionally credited to Zhang Heng, who built a seismoscope in 132 CE in ancient China. It reportedly used a mechanism with metal balls and dragons to indicate the direction of a distant quake. While it did not record waveforms like a modern seismograph, it was an extraordinary early instrument for detecting seismic activity. Modern seismographs were later developed in the 19th century.
