When I run all scenarios, the hazard curves appear to have more spatial variance than the USGS hazard curves, and they do not recreate the hazard curves. How can I get the spatial correlation to match?

Kuanshi,
Thank you so much for this quick response! I have not used the OpenSHA logic tree at all but could look into shifting to that if it is preferable.
Thanks,
Emily

Hello,
When I run the hazard simulation (I am using the developer's version to run multiple scenarios at once, but I believe this applies regardless) I end up sometimes with 'Point2Vert_SS_FaultPoisSource' as the fault name. I am wondering if there is a way to exclude this from the scenarios so I end up with realistic distances to actual known faults in the area. Sometimes I do get Hayward, San Andreas, Calaveras, etc., but I would like specifically to exclude these point sources.
Thanks,
Emily

Hi Steve,
I have had this error a few more times, and others are having the same error on theirs, which they have just downloaded over the weekend. The whole app crashes when clicking Run Hazard Simulation without any error message or files created as output. It is also doing it when the Record Selection is not set to None, so I am not sure what is triggering the crash. They also have java downloaded.
Thanks,
Emily

Regional Hazard Simulation (R2D, rWhale) / Length of value error
« on: April 07, 2022, 08:10:08 PM »
I am running a larger number of simulations (40) using the backend with the attached input files and calling 'python C:\path\to\HazardSimulation.py --hazard_config  C:\path\to\EQHazardConfiguration.json'

I end up with this error: ValueError: Length of values (800) does not match length of index (1280)

Is there something wrong in my inputs?

Steve,
Here is a screenshot of inputs that worked- when I changed that dropdown that you mentioned to None, then hit Run Hazard Simulation, that is when the whole tool would crash. I have also included the input building locations file.

I do not need a time history output, however R2D crashes every time I set the dropdown menu to 'None'. I tried varying other inputs but that seems to be the one causing the crash.

Regional Hazard Simulation (R2D, rWhale) / Re: Simulated hazard magnitude

Kuanshi,
That makes sense. I would be interested in having R2D be able to run a series with different scenarios for each job. Ideally, a distribution would be useful so when choosing minimum and maximum magnitudes, they have associated frequencies which could reflect the probabilities of various events, but even just a uniform likelihood that each ground motion map comes from some magnitude event within those bounds would be useful.

The way I am using R2D now to simulate ground motions, it seems I need to run scenarios one-by-one and set the bounds from e.g. 7.0 to 7.2 if I want a ~M7.1 event and need to run multiple jobs if I want events reflecting magnitudes between 7.0 and 8.5. Essentially, I am finding liquefaction probabilities and want to know its dependence on the earthquake magnitude along with other parameters, so I want a distribution of magnitudes.

Ultimately, it would be useful to be able to put in a probability distribution so the output ground motions, if running a large enough number, would reflect the likelihood of the events themselves.

Let me know what you think would be possible or if you have other suggestions of how I can use the tool as-is to get these types of outputs more efficiently.
Thanks,
Emily

Regional Hazard Simulation (R2D, rWhale) / Re: Simulated hazard magnitude

Kuanshi,
Thank you- this was helpful! To clarify- there is just one magnitude no matter how many scenarios are run?

Regional Hazard Simulation (R2D, rWhale) / Simulated hazard magnitude
« on: February 02, 2022, 02:04:15 AM »
I am wondering if the actual magnitude of the simulated events is available somewhere in the outputs of a set of hazard simulations. For example, if I input to get events from M = 7.0 to M = 8.0 and run 5 scenarios, is there (or could there be) a list somewhere of what magnitudes were chosen for the 5 runs?

Steve,
Thank you- I see the attachments now. I am wondering for the event grid if it needs to point to .csv files, or if there is only one IM, can the first column be that value?

Hello,
I cannot find information on the implementation of ground failure beyond the blurb in the user manual- I am curious how ground failure is defined, if Vs30 or any other inputs are included (GWT?). I also see in the example that the spreading and settlement is estimated from PGA, but the manual says that PGD must be provided, so what are those functions and what do they take as input?

Hi Steve,
Sorry for the late reply- I did not see these until now. I do not have the fragility curves in the right format, but here is a .csv with the parameters. All units are in meters for the IM depth. I don't see the attachment for the .json format.
Thanks,
Emily

I would like to be able to run a regional simulation for tsunami hazard with normal and lognormal fragility functions for 3 damage states and depth as the input intensity measure.

Kuanshi,
Of course, here they are!
