SPECFEM
SPECFEM is a suite of simulation open-source codes designed to model how seismic waves travel through the Earth. It includes versions such as: SPECFEM3D and SPECFEM C++, each tailored for specific use cases.
Using the spectral-element method, these codes accurately capture complex geological features like mountains, basins, and underground faults.
Scientists rely on SPECFEM to create detailed maps of shaking intensity, improving earthquake preparedness and hazard assessment. It is also used in fields like volcanology, subsurface imaging, and even medical ultrasound testing.
Seismoacoustic wave model of an underwater explosion detonated by the French Navy in the Rade d’Hyères, southern France.
Classical benchmark model “Marmousi”, featuring multiple geological layers. It illustrates the interaction between seismic waves and complex subsurface structures over time.
