New hazard charts in General Analysis

Two new charts have been added to the General Analysis application related to assessing hazard with the frequency-magnitude relationship. The new charts plot various hazard parameters over time, or, by time of day:                 Charts / Time Series / Hazard over Time                 Charts / Diurnal / Diurnal Hazard The following parameters can be plotted …

Stochastic declustering explained

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 …

New background filters

We have added some new event filter options to general analysis related to ‘background’ activity. ‘Background’ events are generally defined as having low variability in space and time. The new background filters aim to identify events that are clustered in space and time and the user can either display the ‘clustered’ or the ‘background’ component …
