Scenario Damage Outputs#

The Scenario Damage Calculator produces the following output file for all loss types (amongst “structural”, “nonstructural”, “contents”, or “business_interruption”) for which a fragility model file was provided in the configuration file:

  1. Event Damages: this file contains the damage distribution statistics for each individual events generated by the scenario, for each event and for every GMPE specified in the job file. For each event, the total number of buildings in each damage state are listed in this file.

  2. Average Asset Damages: this file contains the damage distribution statistics for each of the individual assets defined in the Exposure Model that fall within the region and have a computed Ground Motion Field value available within the defined asset_hazard_distance. For each asset, the mean number of buildings (mean) in each damage state are listed in this file.

In addition, if the OpenQuake-QGIS plugin is used for visualizing or exporting the results from a Scenario Damage Calculation, the following additional outputs can be exported:

  1. dmg_by_tag: this file contains the aggregated damage distribution statistics for each of the tags defined in the Exposure Model. For each tag, the mean number of buildings (mean) in each damage state are listed in this file.

  2. dmg_total: this file contains the aggregated damage distribution statistics for the entire portfolio of assets defined in the Exposure Model. The mean (mean) and associated standard deviation (stddev) of the total number of buildings in each damage state are listed in this file.

In addition to the above asset-level damage output file which is produced for all Scenario Damage calculations, the following output file is also produced for all loss types (amongst “structural”, “nonstructural”, “contents”, or “business_interruption”) for which a Consequence Model file was also provided in the configuration file:

  1. Event Losses: this file contains the scenario consequence statistics for each of the individual events generated by the scenario for every GMPE specified in the job file. For each event, the total consequences considering the entire portfolio of assets are listed in this file.

  2. Average Asset Losses: this file contains the scenario consequence statistics for each of the individual assets defined in the Exposure Model that fall within the region and have a computed Ground Motion Field value available within the defined asset_hazard_distance. For each asset, the mean consequences (mean) and associated standard deviation (stddev) are listed in this file.

In addition, if the OpenQuake-QGIS plugin is used for visualizing or exporting the results from a Scenario Damage Calculation, the following additional outputs can be exported:

  1. losses_by_tag: this file contains the aggregated scenario consequence statistics for each of the tags defined in the Exposure Model. For each tag, the mean consequences (mean) and associated standard deviation (stddev) are listed in this file.

  2. losses_total: this file contains the aggregated scenario consequence statistics for the entire portfolio of assets defined in the Exposure Model. The mean consequences (mean) and associated standard deviation (stddev) are listed in this file.

If the calculation involves multiple Ground Motion Prediction Equations as described in Example 4 in Section Scenario Damage Calculator, separate output files are generated for each of the above outputs, for each of the different Ground Motion Prediction Equations used in the calculation.

These different output files for Scenario Damage calculations are described in more detail in the following subsections.

The output file lists the total number of buildings in each damage state for each simulated event for the scenario, for each GMPE specified in the job file.

Asset damage statistics#

This output contains the damage distribution statistics for each of the individual assets defined in the Exposure Model that fall within the region and have a computed Ground Motion Field value available within the defined asset_hazard_distance. An example output file for structural damage is shown in the file snippet in the table below.

The output file lists the mean of the number of buildings in each damage state for each asset in the exposure model for all loss types (amongst ‘structural’’, “nonstructural”, “contents”, or “business_interruption”) for which a Consequence Model file was also provided in the configuration file in addition to the corresponding Fragility Model file.

Damage statistics by tag#

If the OpenQuake-QGIS plugin is used for visualizing or exporting the results, the Scenario Damage calculator can also estimate the expected total number of buildings of a certain combination of tags in each damage state and made available for export as a csv file. This distribution of damage per building tag is depicted in the example output file snippet in the table below.

The output file lists the mean of the total number of buildings in each damage state for each tag found in the exposure model for all loss types (amongst “structural”, “nonstructural”, “contents”, or “business_interruption”).

Total damage statistics#

Finally, a total damage distribution output file can also be generated if the OpenQuake-QGIS plugin is used for visualizing or exporting the results from a Scenario Damage Calculation, which will contain the mean and standard deviation of the total number of buildings in each damage state, as illustrated in the example file in the table below.

The output file lists consequence statistics for all loss types (amongst “structural”, “nonstructural”, “contents”, or “business_interruption”) for which a Consequence Model file was also provided in the configuration file in addition to the corresponding Fragility Model file.

Total consequence statistics#

Finally, if the OpenQuake-QGIS plugin is used for visualizing or exporting the results from a Scenario Damage Calculation, a total consequences output file can also be generated, which will contain the mean and standard deviation of the total consequences for the selected scenario, as illustrated in the example shown in the table below.
