This page contains a basic description of some of the data products produced by the Broadband Platform while running a simulation. All the data products described below will be in the outdata directory after a simulation completes.

Scenario Simulations

Scenario simulations are hypothetical simulations, what-if scenarios. Users provide a source description file describing the rupture and a station list file containing stations for which ground motions will be calculated.

Station Map

A map showing the fault trace along with the stations for which ground motions are calculated. The yellow star shows the hypocenter location.

Velocity and Acceleration Seismograms

The Broadband Platform will produce both velocity and acceleration seismograms in BBP format for each station. An example is shown below.

Validation Simulations

Validation simulations can be used to calculate seismograms from historical events and compare these again recorded ground motion data, allowing scientists to develop and validate their methods. For this reason, only locations where recorded ground motions are available can be used. In addition to all data products described above for scenario simulations, the following data products will also be calculated:

Seismogram Comparison Plots

Plots showing calculated data (in red) along with observation data (in black). The two bottom plots show a comparison of the arias duration between simulations and recorded data.
