Fault Physics Lab
Machine-translated · View original
A lab that models fault behavior based on rock friction and fracture.
AboutAbout the lab
Making physical models of faults more reliable.
The Fault Physics Lab builds physical models and analyzes their behavior in order to understand and make use of the various phenomena that accompany fault motion.
The lab studies the mechanics of rock fracture and friction using theory, numerical simulation, observation, and experiments.
Key terms
- Friction
- The force that resists slip when a fault slides. Its strength changes with factors such as slip velocity.
- Earthquake cycle
- The repeating process in which strain accumulates on a fault, an earthquake occurs, and strain begins to accumulate again.
- Slow earthquake
- A phenomenon in which a fault slips much more slowly than in an ordinary earthquake.
ResearchResearch themes
The lab studies the mechanics of rock fracture and friction through theory, numerical simulation, observation, and experiments in order to refine physical models of faults.
*Illustrative imageRefining physical models of faults
To understand and make use of the various phenomena that accompany fault motion, the lab aims to build physical models and analyze their behavior, studying the mechanics of rock fracture and friction through theory, numerical simulation, observation, and experiments.
*Illustrative imageFriction laws and earthquake cycles
Using numerical simulations of earthquake cycles, the lab investigates the behavior of rate- and state-dependent friction laws, the diversity of slow slip before earthquakes, and fault instability in viscoelastic media.
*Illustrative imageSubduction zone fluids and slow earthquakes
Based on hydraulic models, the lab estimates the steady-state effective normal stress in subduction zones and examines its relationship to slow earthquakes occurring at shallow depths (collaborative research).
