Fault-based analysis app

The intention of this app is to help understand which faults are triggered by nearby blasting and to quantify the hazard associated with each fault on excavations. Understanding and quantifying the role of structures on your seismicity is critical in assessing your current seismic risk, and the risk with future excavations near active faults. Numerical models should reflect the seismic behaviour that is observed on key structures. The app may also be useful to determine which structures should be included explicitly in numerical modelling and measured for calibration.

The app includes three ways of ranking seismic faults:

  1. Blast Productivity. The amount of seismicity generated by the fault given the amount of nearby blasting.
  2. Fault Source Hazard. The likelihood of a large event on the fault.
  3. Fault Excavation Hazard. The likelihood of a strong ground motion due to seismicity on the fault.
