Regional Hazard Simulation (R2D, rWhale) / About earthquake scenario simulation output
« on: June 06, 2023, 06:54:24 PM »
Hello all,

When conducting earthquake scenario simulation with R2D, I couldn't find the earthquake rupture location or rupture id, source id of the simulated earthquake. Is there any output file that record this information?

Moreover, I ran 10 scenarios but only got 1 magnitude value and 2 identical SiteSourceDistance values in SiteIM.json file. I would like to know that is all the scenarios have same magnitude and same rupture location?

Thanks in advance for your help!

Regional Hazard Simulation (R2D, rWhale) / Scenario information
« on: May 19, 2023, 02:31:54 AM »
Hello all,

The hazard simulation output file SiteIM.json only contains the magnitude and the meanAnnualRate of the Scenario. Is there any other file that could find the other information of the Scenario? such as the Rupture Name, location, depth of the earthquake event, which UCERF3 logic tree branch it belongs to, etc.

Moreover, for one Scenario with multiple ground motions per site (e.g. 10), the output files will contain 10 ground motion sets and 10 siteIM sets respectively (each set contains one ground motion and one siteIM for each site).

I am wondering if that means to compute the ground motion map ten times, and each ground motion set and siteIM set were computed by each of the ground motion map respectively? Or is there another way to compute the site IM and ground motion set?

Thanks for reading and look forward to your reply!

Regional Hazard Simulation (R2D, rWhale) / About UCERF3 Earthquake Scenario Simulation

Hello all,

Is there any example for UCERF3 Earthquake Scenario Simulation? I always encounter error warning when applying Earthquake Simulation by UCERF3. I will really appreciate it if you could share any pertinent example or have any advice about this.

Moreover, to only run HAZ hazard similuation, do I need to define other information like VIA, ASD, HTA, MOD, ANA, etc? Or only the GI and HAZ information is enough for runing the hazard simulations?

Regional Hazard Simulation (R2D, rWhale) / About Scenario number
« on: May 17, 2023, 09:24:25 PM »
Hello all, When I check the manual for R2D, I saw a blank for seeting Scenario number in R2D-HAZ-Earthquake Scenario, as shown in Fig. 2.3.1.10 Earthquake rupture forecast.https://nheri-simcenter.github.io/R2D-Documentation/common/user_manual/usage/desktop/R2DTool/HAZ.html#id20

However, when I apply R2D software, 2.1.0 version, I couldn't find this blank. Is this setting deactivated? or It is has the same meaning of number of ground motion per site in R2D-HAZ-Site?
