We obtain a cohesive zone length of 70% of the slip-pulse length and a rupture velocity of 90% of the shear-wave speed. This correspond to an estimated energy release rate of 5.8MJ/m^2. This is the first time this key parameter of rupture dynamics is measured directly on fault.

Then we used the interpolated slip-rate function as an input for a steady-state propagating pulse elastodynamic model, which allowed to estimate the stress-slip history and the breakdown work.

We have tracked the motion of some landmarks across the fault to measure the slip function and the slip rate function:

Here is the same thing, done with the motion of the small poles that move just behind the grid in the right.

I've been trying to estimate the slip rate function, using the motion of the large pillar and using the wall of the portal as reference.

Here is the same analysis, but this time I used the motion of the small poles that one can see moving behind the grid in the right low corner of the image. I made the assumption that the bars of the grid where 10cm appart.

I have been doing the same type of analysis. Here is slip and dlip rate inferred from the motion of the pillar in the background, taking the wall of the portal arche as a reference. (I made the hypothesis that the pillar is 40cm wide, and did not take into account and angle of sight effects)
