“…Viscoelastic models feature the following characteristics that make them useful in the investigation of different aspects of the seismic cycle: Figure 4. Examples of seismotectonic scale models: (a) viscoelastic gelatine wedge set-up used by Corbi et al (2013) to study subduction megathrust earthquakes (modified from there); (b) elastoplastic granular wedge set-up used in this study to simulate subduction megathrust seismotectonic evolution, which is developed from a similar set-up used by Rosenau et al ( , 2010, and the resulting earthquake deformation pattern (side view, modified after ; (c) layered elastic-viscoelastic foam rubber-silicone wedge set-up used by Dominguez et al (2015) to study subduction megathrust earthquakes and the resulting earthquake deformation pattern (top view; left: displacement; right: pseudo-InSAR fringe pattern); (d) layered elastic-viscoelastic foam rubber-silicone strike-slip set-up used by Caniven et al (2015) and the resulting earthquake deformation pattern (top view; left: displacement; right: pseudo-InSAR fringe pattern) (modified from Caniven et al, 2015).…”

Analogue earthquakes and seismic cycles: experimental modelling across timescales

Abstract. Earth deformation is a multi-scale process ranging from seconds (seismic deformation) to millions of years (tectonic deformation). Bridging short-and long-term deformation and developing seismotectonic models has been a challenge in experimental tectonics for more than a century. Since the formulation of Reid's elastic rebound theory 100 years ago, laboratory mechanical models combining frictional and elastic elements have been used to study the dynamics of earthquakes. In the last decade, with the advent of high-resolution monitoring techniques and new rock analogue materials, laboratory earthquake experiments have evolved from simple spring-slider models to scaled analogue models. This evolution was accomplished by advances in seismology and geodesy along with relatively frequent occurrences of large earthquakes in the past decade. This coincidence has significantly increased the quality and quantity of relevant observations in nature and triggered a new understanding of earthquake dynamics. We review here the developments in analogue earthquake modelling with a focus on those seismotectonic scale models that are directly comparable to observational data on short to long timescales. We lay out the basics of analogue modelling, namely scaling, materials and monitoring, as applied in seismotectonic modelling. An overview of applications highlights the contributions of analogue earthquake models in bridging timescales of observations including earthquake statistics, rupture dynamics, ground motion, and seismic-cycle deformation up to seismotectonic evolution.

Experimental Study of Stick‐Slip Failure Processes and Effect of Physical Properties on Stick‐Slip Behavior

et al. 2018

To investigate the process of stick‐slip shear failure, small‐scale poly methyl methacrylate samples with friction faults and a high‐speed recording experiment system are used. The evolution of shear stress and slip displacement clearly shows both the propagation of stick‐slip failures and the local slip‐weakening behavior of the fault. The distribution of local stress ratio τyx/σy along the fault is of great significance to determining the nucleation location. The interrelations among local shear stresses, slip displacements, slip velocities, and slip accelerations show the details of local deformations and motions of breakdown near the crack tip. Four distinctive phases of local breakdown process are found in both the nucleation zone and the dynamic rupture propagation zone. Experiments with three prefabricated roughnesses of the fault surfaces are conducted at normal stresses varying from 2 MPa to 4 MPa. The critical crack length decreases and the rupture velocity increases with increasing normal stress or decreasing the roughness. Both the local dynamic stress drop Δτd and local breakdown stress drop Δτb generally increase with increasing normal stresses and decrease with increasing the roughness. Although the critical slip‐weakening displacement uc seems to be insensitive to normal stress, it decreases as the fault becomes smoother. The shear fracture energy Gc, which is determined by Δτb and uc, increases with an increase in the normal stress and increases with increasing the roughness. In addition, the linear relations of Δτd, Δτb, and uc to the static friction coefficient μs are found, and a quadratic function relating Gc and μs is established.
