Code template for the Australian Probabilistic Tsunami Hazard Assessment 2018

This template contains codes used for the 2018 Australian PTHA. It does not contain the actual data or model results, because these files would be very large and unsuitable for a git repository. However, see this page for information on accessing the results.

The sub-folders below all contain relevant scripts and README information:

DATA is used for data that has been 'processed' or developed for modelling [e.g. sourcezone contours, edited DEMs, etc]. It should not contain RAW data, (the latter instead goes in '../../DATA/')

SOURCE_ZONES is used for the unit source initial conditions and tsunami runs for every source-zone. This is the bulk of our modelling results.

EVENT_RATES contains code to compute the rate of earthquakes on each source-zone, the tsunami wave height exceedance rates at each hazard point, etc.

The analysis proceeds by defining the geometry of one or source zones (with SOURCEZONE_CONTOURS and SOURCEZONE_DOWNDIP_LINES), and making a DEM and hazard points for tsunami modelling (see DATA).

Next, we can make a suite of tsunami events on each source-zone, by following the procedures in SOURCE_ZONES. This is the most time consuming and computationally intensive part of the analysis, and super-computer access is basically essential for multi-source analyses involving large source-zones.

Finally, we can compute rates for each of these events, and compute various tsunami hazard metrics at our hazard points, using code in EVENT_RATES.
