When an earthquake occurs, ground vibrations activate the system, causing the staff to tilt or move. This movement triggers the dragons to open their mouths, releasing the copper balls. The released balls then fall into a basin below, providing a visual signal to observers. The number and position of the dragons that release their copper balls help determine the direction and intensity of the seismic event.

This innovative design, combining symbolic imagery with practical function, allowed ancient Chinese scholars to monitor seismic activity effectively. The dragon and staff system exemplifies the sophisticated engineering methods used to detect and interpret earthquakes in ancient China without modern technology.

How the design detects and indicates seismic activity

The ancient Chinese seismograph design employed a sophisticated system to detect seismic activity through mechanical movement. When an earthquake occurs, vibrations cause internal components to shift, triggering a visible indicator.

This system primarily utilized a series of pendulums and levers that responded to ground motion. These elements would transfer seismic energy into mechanical motion, enabling the instrument to "detect" vibrations reliably.

A key feature involved the twelve dragons, each holding a copper Tits, positioned above a central axis. When seismic waves caused ground movement, the structure’s internal mechanism would activate a specific dragon, signaling the direction and presence of the earthquake.

The detection process was further enhanced by the copper Tits, which moved with the dragons. These components served as visual indicators, often causing a ball to fall into a designated container, thus "indicating" the seismic event. This intricate design allowed ancient Chinese seismographs to precisely record seismic activity with remarkable reliability.
