Part 8: Earthquakes & Seismology
Seismic Earth
Earthquakes are sudden releases of elastic strain energy along faults. Seismology—the study of seismic waves—reveals Earth's internal structure, quantifies earthquake sources, and underpins hazard assessment. From the elastic rebound theory to moment tensors, this part covers the physics of earthquakes and what they tell us about tectonics.
