The first seismograph was invented in China by Zhang Heng in 132 AD. It worked using a pendulum mechanism where a suspended pendulum would swing in response to ground motion caused by an earthquake, triggering a mechanism that would drop a ball into one of eight dragon mouths, indicating the direction of the quake.
