This project aims to decipher the physics of faulting and earthquakes from damage zones around seismogenic faults. It will examine a mechanism for instability in solids: volumetric collapse due to a dissipative pressure wave. This pressure wave may control damage-zone geometry and relate to earthquake stress and rock material properties. The project will research the instability through theoretical, laboratory and field studies. Anticipated outcomes include advances in earthquake and fault prediction, tools to determine the stress state and material properties of Earth’s crust, and knowledge of a class of solid instabilities.

该项目旨在从发震断层周围的破坏区解读断层和地震的物理原理。它将研究固体不稳定的机制：耗散压力波导致的体积塌陷。这种压力波可以控制损伤区的几何形状，并与地震应力和岩石材料特性相关。该项目将通过理论、实验室和现场研究来研究不稳定性。预期成果包括地震和断层预测方面的进展、确定地壳应力状态和材料特性的工具以及一类固体不稳定性的知识。
