Live Fault Table
Earthquakes occur when accumulated tectonic stress exceeds fault resistance; released energy depends on several source factors, P and S waves travel differently, and observed impact emerges through source, path, site, and structure.

What your child will figure out
- Load a fault model until stress exceeds resistance without directly commanding rupture.
- Explain released energy using stored strain, stiffness, slipped area, and displacement rather than friction alone.
- Use P-before-S arrivals and growing P–S gaps as sensor evidence of distance.
- Distinguish identical shaking input from structure-dependent response across the source–path–site–structure chain.
The levels
- Load the fault
Explore a tactile fault and observe slip only after accumulated stress exceeds resistance.
- Energy is a team
Compare two automatically slipping faults with all source factors visible.
- Wave arrivals
Read P and S arrivals at near, middle, and far sensors after a loaded fault slips.
- Same input, new response
Apply one immutable recorded shaking input to two different structures.
- Tell the whole quake story
Attribute evidence across source, path, site, and structure on an unfamiliar case.
Ready when they are.
