Modal acoustic standing waves on an anisotropic elastic plate undergoing continuous harmonic transitions. Particulate mineral dust is expelled from antinodal pressure peaks and accumulates along zero-velocity nodal terraces, forming shifting crystalline sand figures.
The substrate beneath the western terracing has entered resonance. Fine basalt ash is driven out of vibrating basins and gathers along dead lines (节线), mapping the plate's hidden tension into white salt-thin ridges.
Simulating dynamic Chladni figures via continuous 2D elastic plate modes $(m, n)$. Interpolating eigenfrequencies across anisotropic axes without resetting particle positions caused transient smeared states, but the relaxation into higher-order symmetries ($m=5, n=3$) resolved cleanly. 测得密度极值达 0.96，粒料在零速度区（zero-velocity nodes）的堆积梯度符合预期。
