Geophysics Lab
Ten interactive experiments covering gravity, seismology, magnetism, heat flow, geodynamics, and integrated geophysical methods. Physically accurate simulations with real-time parameter control.
Buried Sphere Detection
Explore how a buried sphere of anomalous density distorts the surface gravity field. Adjust depth, radius, and density contrast to model ore bodies, salt domes, and hidden voids.
Latitude · Free-Air · Bouguer
Apply standard gravity corrections step-by-step: latitude, free-air, and Bouguer reductions along a simulated traverse to reveal subsurface density anomalies.
P · S · Rayleigh · Love
Visualize seismic wave propagation with animated particle motion for P-waves, S-waves, Rayleigh, and Love waves. View synthetic seismograms in real time.
Layer Velocity Analysis
Simulate seismic refraction surveys with ray-tracing through layered media. Build travel-time curves and compute layer depths using the intercept-time method.
GAD Model & IGRF
Explore the Geocentric Axial Dipole model and IGRF reference field. Visualize field lines, compute inclination, declination, and intensity at any location on the globe.
Seafloor Spreading & APWP
Animate magnetic reversal stripes from seafloor spreading. Explore the Geomagnetic Polarity Time Scale (GPTS) and track Apparent Polar Wander Paths.
Geotherms & Borehole Data
Model steady-state and transient geotherms with radiogenic heat production. Simulate borehole temperature measurements with noise and compare tectonic settings.
Finite-Difference PDE Solver
Run a 2D thermal convection simulation using finite differences. Visualize temperature fields, velocity streamlines, and explore Rayleigh number effects on mantle dynamics.
Airy · Pratt · Flexural
Compare Airy, Pratt, and flexural isostatic models. Simulate glacial loading and post-glacial rebound with time-dependent viscous response of the mantle.
Integrated Geophysical Model
Build an integrated crustal model of the Malawi Rift combining gravity, magnetics, seismic, and topographic data. Explore East African Rift tectonics.
