Disaster modeling

Currently you can model earthquake, flooding and fire in ERAD. Fire model is still under development and documentation is not included for fire for now.

Simulating earthquake

The snippets below shows an example for simulating earthquake in ERAD.

import datetime 

from erad.db import neo4j_
from erad.db import inject_earthquake
from erad.db import disaster_input_model

# Make sure to update the url, username and password
neo4j_instance = neo4j_.Neo4J(
                neo4j_url='bolt://localhost:7687',
                neo4j_username='neo4j', 
                neo4j_password='neo4j')


earthquake = disaster_input_model.PointEarthquake(
            longitude=-121.72125955960196, 
            latitude=37.92770173811863,
            timestamp=datetime.datetime(2022, 1, 1, 0, 0,0),
            magnitude=6.0,
            depth=15.0
        )

inject_earthquake.inject_point_earthquake(
        earthquake, neo4j_instance.driver,
        critical_infras=["Grocery", "Hospital","Convenience", "Shelter", "Banking"])

We first created a neo4j database instance by passing neo4j host url, username and password. Secondly we defined input model for point earthquake by passing relevant input parameters. Lastly inject_point_earthquake takes the input, database driver and list of critical infrastructure which need to be updated following the simulation.
