This example provides a small damage calculation for a scenario earthquake. The example is limited to one 10-arcsec cell.
## Run the example
Please refer to [README.md](../../README.md) for information on the program requirements and how to install them.
To run the example calculation, please execute the script
`run_example_cell.sh`.
Use
`python3 damage_calculator.py --help`
for information on how to use the program input options.
## Input files
`exposure.csv`: Represents the exposure model with each row providing information for one asset. Each asset in the exposure model is represented by its location, a taxonomy string describing the structural properties of the asset and the number of buildings representing the asset.
`cell_ids.csv`: Contains all unique cell IDs used in the exposure model.
`ground_motion_values.csv`: Contains the ground-motion values for the example area.
`polygons.csv`: Contains geometries of the cells in the exposure model along with their cell IDs. The geometry in this example is the 10-arcsec cell.
`taxonomy_mapping.csv`: Contains the mapping between the taxonomies of the exposure assets and the names of the fragility functions. The mapping is courtesy of Dr. Helen Crowley (Eucentre, Pavia, Italy).
`fragilities`: This folder contains all the fragility functions needed for the taxonomies in the exposure model, according to the mapping in `taxonomy_mapping.csv`. The fragility functions are stored as CSV files under `./data/fragilities/`. The fragility models used in this example have been authored by [L. Martins and V. Silva (2020): Development of a fragility and vulnerability model for global seismic risk analyses, Bulletin of Earthquake Engineering](https://doi.org/10.1007/s10518-020-00885-1).

## Output
The example script writes the damage calculation into `result.cvs`. This output can be compared with a pre-computed reference output in `reference_result.csv` showing the expected result of the example calculation.
