Earthquake Shaking for a soil erosion

Simulate a soil erosion live in your browser. This runs the real Earthquake Shaking solver — adjust the inputs, watch it respond instantly, and export the result. No install, no account.

Earthquake Magnitude & ShakingLive

Controls

Presets

Magnitude is logarithmic in amplitude but each unit releases about 32× more energy (E ∝ 10^1.5M). Shaking at a site falls off with distance through attenuation. Peak ground acceleration maps to the Modified Mercalli intensity people actually feel — a planning estimate, not a site-specific hazard analysis.

Governing equation

Reading this result: 30 km out, an M6 quake attenuates to only ~0.3%g — intensity III-IV Light, felt but rarely damaging. Distance and the log falloff tame most of the 6.3e+13 J released.

About this simulation

The full Earthquake Shaking tool models a soil erosion with the same numerics engineers and scientists use — running entirely client-side. Change any parameter and the result updates in real time, so you can build intuition, check a design, or teach the concept without spreadsheets or installs.

Frequently asked questions

How do I simulate a soil erosion?
Open this page and use the live Earthquake Shaking tool below — set your inputs and the simulation runs instantly in your browser using real numerics. No install, no account needed.
Is it free?
Yes. The simulation runs free in your browser. A one-time unlock or a Pro plan adds advanced parameters, saved presets, data import, and clean exports.
Can I use my own numbers?
Absolutely — every input is adjustable, and with data import you can drive a soil erosion from your own measurements.
