Modeling the full spectrum of observed seismicity: Insights from friction laws, fault instability, and fault-zone mechanics

Navid Kheirdast and edited by Alexis Gauthier June 17, 2026

Introduction Despite advances in our understanding of rock mechanics, the frictional behavior of rocks, and the physics of instability in geological materials, the coexistence of slow and fast earthquakes, as well as various types of fault-zone seismic radiation such as tremor, remains enigmatic. Can fault mechanics and friction laws reproduce the full spectrum of observed seismicity? In this week ...[Read More]

Have you ever wondered what common thing connects fault surfaces and their characteristics with your… squeezy sneakers on a wet surface or the required frequent change of your car tyres? Well, the answer is simple. The fundamental principles of stress and friction can significantly cause this behaviour in our everyday lives. However, these two factors can also be responsible for the slip behaviour ...[Read More]
