How Does it Work? - Seismograph

Jamie embarks on a journey to understand seismographs, devices that detect and record earthquakes. She learns about inertia's role in their function, how to interpret seismograms, and the evolution of digital seismographs. Her exploration reveals how seismologists decode Earth's vibrations to understand its inner workings, highlighting the importance of these devices in providing timely warnings and insights into our planet's dynamics.
