On the need to integrate interannual natural variability into coastal multihazard assessments
Abstract The co-occurrence of multiple hazards can either exacerbate or mitigate risks. The interrelationships between multiple hazards greatly depend on the spatiotemporal scale and can be difficult to detect from large to local scales. In this paper, we identified coastal regions worldwide where t...

Abstract The co-occurrence of multiple hazards can either exacerbate or mitigate risks. The interrelationships between multiple hazards greatly depend on the spatiotemporal scale and can be difficult to detect from large to local scales.

We classified the results at the national and municipal levels, with a focus on multiple hazards simultaneously occurring in space and time.
