Various techniques are described utilizing one or more unmanned aerial vehicles (UAVs, or “drones”) for various disaster and/or catastrophe-related purposes. UAVs may collect data in an attempt to predict the occurrence and/or extent of a catastrophe and/or to mitigate the impact of a catastrophe before and, if not at that time, once it has occurred. The UAVs may perform various tasks such that the damage to property caused by a catastrophe (or potential catastrophe) may be eliminated or mitigated. The drone data may be transmitted by the UAVs to an external computing device, which may be associated with an insurer and used, with an insured's permission, to begin and/or facilitate an insurance claim process or other various insurance-related tasks. Damage to insured property may be estimated from the drone data, and proposed or estimated insurance claims may be generated for customer review, modification, or approval.
