He called it an earthquake weathercock. each of the eight dragons had a bronze ball in its mouth. They founded the seismological society of japan, which funded the invention of seismographs. By the chinese astronomer and mathematician chang heng. Richter is most famous as the creator of the richter magnitude scale, which, until the development of the moment magnitude scale in 1979, quantified the size of earthquakes. Heng's invention was called the dragon jar (see picture above). The cecchi seismograph also used pendulums, but it was the first to record the relative motion of the pendulums with respect to earth’s ground motions as a function of time. Web the first known earthquake detector was invented in 132 a.d.
