The RESOLVE project: a multi-physics experiment with a temporary dense seismic array on the Argentière Glacier, French Alps
Florent Gimbert, Ugo Nanni, Philippe Roux +11
Recent work in the field of cryo-seismology demonstrates that high frequency (>1 Hz) waves provide key constraints on a wide range of glacier processes such as basal friction, surf…
High Resolution Long- and Short-Term Earthquake Forecasts for California
M. J. Werner, A. Helmstetter, D. D. Jackson +1
We present two models for estimating the probabilities of future earthquakes in California, to be tested in the Collaboratory for the Study of Earthquake Predictability (CSEP). The…
Afterslip and aftershocks in the rate-and-state friction law
Agnes Helmstetter, Bruce E. Shaw
We study how a stress perturbation generated by a mainshock affects a population of faults obeying a rate-state friction law. Depending on the model parameters and on the initial s…
Relation between stress heterogeneity and aftershock rate in the rate-and-state model
Agnes Helmstetter, Bruce E. Shaw
We estimate the rate of aftershocks triggered by a heterogeneous stress change, using the rate-and-state model of Dieterich [1994].We show that an exponential stress distribution P…
Creep failures in heterogeneous materials
H. Nechad, A. Helmstetter, R. El Guerjouma +1
We present creep experiments on fiber composite materials with controlled heterogeneity. Recorded strain rates and acoustic emission rates exhibit a power law relaxation in the pri…
Andrade and Critical Time-to-Failure Laws in Fiber-Matrix Composites: Experiments and Model
H. Nechad, A. Helmstetter, R. El Guerjouma +1
We present creep experiments on fiber composite materials. Recorded strain rates and acoustic emission (AE) rates exhibit both a power law relaxation in the primary creep regime an…
