Seismic tomography

Seismic tomography is a method used to create images of the Earth's interior by analyzing seismic waves produced by earthquakes or man-made sources. Just as a CT scan takes pictures of the human body, scientists use sensors to record how these waves travel through different materials. By studying their speed and how they change direction, researchers can map variations in the Earth's structure, such as identifying solid rock, molten magma, or even faults. This information helps us understand geological processes and assess risks related to earthquakes and volcanic activity.
