Global Seismology

Advancing Earth & Planetary Sciences using Seismology

We develop & disseminate resources from planetary-scale seismological research in collaboration with scientists worldwide.

Seismology is our primary tool for understanding various phenomenon that shape the Earth's deep interior. It also helps characterize natural hazards such as earthquakes and landslides that emanate vibrations in the solid Earth. The method of seismic tomography uses waves generated by earthquakes to image the Earth’s interior in a manner similar to CT scanning of the human body. Routine calculations for earthquake magnitudes and early warning systems also need Earth models. This portal contains data, documentation, software and models that are used for various applications in the geosciences and beyond.
