Reset variables and filters

For a few months now, a new tool has appeared in the General Analysis app; the hanging wall (HW) and footwall (FW) filter. The HW-FW filter allows you to filter your events based on where they are in relation to ticked survey/s. If more than one survey or plane is used for the HW-FW filter, they need to be somewhat parallel in order to make sense.

As mentioned in the last blog post, energy and moment are independently calculated based on the displacement and velocity spectra of the recorded waveforms. Another spectral parameter is the corner frequency.

As mentioned in the last blog post, a stochastic declustering algorithm has been implemented in mXrap to separate events into 'clustered' and 'background' components. It can be useful when designing seismic exclusions and re-entry procedures to separate seismicity that occurs in short bursts from seismicity that has low variability in space and time. Short-term exclusions cannot be used to manage the risk associated with background seismicity, since the hazard inside a potential exclusion would be the same as outside the exclusion. Efficient exclusion and re-entry procedures target areas where seismicity is most clustered and where the seismic hazard to which people are exposed can be reduced with a short disruption to production.
