# Gas facility damage | ||
|
||
**Description** | ||
|
||
This analysis computes gas facility damage based on a particular hazard. Currently supported hazards are: | ||
**earthquake**. | ||
|
||
The process for computing the structural damage is similar to other parts of the built environment. First, a fragility | ||
is obtained based on the hazard type and attributes of the building. Based on the fragility, the hazard intensity at the | ||
location of the building is computed. Using this information, the probability of exceeding each limit state is computed, | ||
along with the probability of damage. For the case of an earthquake hazard, soil information can be used to | ||
modify the damage probabilities to include damage due to liquefaction. | ||
|
||
The outputs of this analysis are CSV file with probabilities of damage and JSON file with information about hazard and fragilities. | ||
