This is a command line utility for extracting time dependent probabilities and equivalent annualized rates from a UCERF3 Fault System Solution.

NOTE: This is only applicable to UCERF3 single branch or branch averaged solutions. It is not applicable to any "true mean" solutions which include alternative geometries for the same faults. Older versions of the branch averaged solutions files do not contain the necessary date of last event data built in and replacements should be downloaded from UCERF3FaultSystemSolutions. An error message will be displayed and the program will exit if one of these older files is used.

Command Line Arguments:

Short Long Required? Description
-d <arg>--duration <arg>yesForecast duration in years.
-y <arg>--start-year <arg>noForecast start year. Default: 2014
-h <arg>--hist-open-interval-basis <arg>noYear basis for historical openinterval. Default: 1875
-p <arg>--prob-model <arg>yesProbability model. One or more of U3_PREF_BLEND,POISSON,BPT_LOW,BPT_MID,BPT_HIGH. Multiple entries can be comma separated.
-s <arg>--solution <arg>yesInput Fault System Solution zip file
-o <arg>--output-file <arg>yesOutput file name
-b--binarynoOutput equivalent annualized rates binary file in FSS rates.bin format. Otherwise CSV format.
-a--filter-aftershocksnoApply aftershock filter
-i--ignore-no-date-lastnoSkips check that ensures date of last event data is set on at least some fault sections. Can be used to calculate time dependent probabilities using only the historical open interval.


To create a CSV file with probabilities and equivalent annualized rates for for each probability model and a 5 year duration:

java -jar ProbDist-1.2.3-10437-2013_11_16.jar --duration 5 --start-year 2014 --solution /path/to/ --hist-open-interval-basis 1875 --prob-model  U3_PREF_BLEND,POISSON,BPT_LOW,BPT_MID,BPT_HIGH --output-file /path/to/output.csv

If you see any error messages that mention java heap space such as an "OutOfMemoryError?" then re-run the command with the -Xmx<MEMORY>G option directly after "java" above, replacing <MEMORY> with the amount of memory in gigabytes that is needed. "-Xmx4G" should be more than adequate if you run into problems.
