The motion of the base with respect to the mass is commonly transformed into an electrical voltage.eismograph. A seismograph, or seismometer, is an instrument used to detect and record earthquakes.

The incredible earthquake detector invented nearly 2,000 years ago. Although we still cannot accurately predict earthquakes, we have come a long way in detecting, recording, and measuring seismic shocks.Many donât realise that this process began nearly 2000 years ago, with the invention of the first seismoscope in 132 AD by a Chinese inventor called Zhang (âChangâ) Heng.he incredible earthquake detector invented nearly 2,000 years ago.
