👉 Seismography, also known as seismic imaging, is a type of scientific research that involves using sound waves to detect and measure changes in Earth's surface. It uses technology such as seismic tomography or seismic wave dispersion to reveal the movement of tectonic plates, faults, and other geological features beneath the earth's surface. The basic principle of seismography is based on the fact that when a loud disturbance (such as an earthquake) occurs deep inside the Earth, it can produce sound waves
