👉 A seismoscope is a device used to detect and measure seismic activity in Earth's crust. It uses a camera that captures images of earthquakes, measuring their intensity and duration. Seismic waves are generated by a tectonic plate sliding across another plate or a solid body, causing vibrations that can be detected by the camera. This technology has been crucial for understanding the movement and behavior of tectonic plates in the Earth's crust.
