How Do Seismographs Work? | Measuring Earth’s Shakes

Seismographs work by suspending a heavy weight that remains stationary due to inertia while the frame and ground move beneath it, recording the relative motion. Earthquakes happen deep underground, but we feel their effects on the surface. To measure these events accurately, scientists use instruments designed to detect even the faintest ground vibrations. These devices

How Do Seismic Waves Travel? | Paths Through Earth Layers

Seismic waves travel outward from a source as energy vibrations, speeding up in dense rock and refracting or reflecting when passing through Earth’s distinct layers. Earthquakes release massive amounts of energy. This energy moves through the planet in the form of waves. These vibrations carry information about the quake itself and the materials they pass
