Abstract
The need for assessing the risk of extreme weatherevents is ever increasing. In addition to quantification of risktoday, the role of aggravating factors such as high popula-tion growth and changing climate conditions matters, too.We present the open-source software CLIMADA (CLIMateADAptation), which integrates hazard, exposure, and vulner-ability to compute the necessary metrics to assess risk andto quantify socio-economic impact. The software design ismodular and object oriented, offering a simple collabora-tive framework and a parallelization strategy which allowsfor scalable computations on clusters. CLIMADA supportsmulti-hazard calculations and provides an event-based prob-abilistic approach that is globally consistent for a wide rangeof resolutions, suitable for whole-country to detailed localstudies. This paper uses the platform to estimate and con-textualize the damage of hurricane Irma in the Caribbean in2017. Most of the affected islands are non-sovereign coun-tries and also rely on overseas support in case disaster strikes.The risk assessment performed for this region, based on re-motely available data available shortly before or hours afterlandfall of Irma, proves to be close to reported damage andhence demonstrates a method to provide readily available im-pact estimates and associated uncertainties in real time.
