Short summary
By considering the quantification of tephra mass deposited on roads following an eruption (or a series of explosive volcanic eruptions), in this work we assessed the cumulated tephra mass on the road networks in three selected towns on Mt Etna’s eastern flank during several paroxysms in 2021. This is a first attempt to estimate the amount of tephra that must be removed during a crisis that could be reused, converting in this way a potential problem into an opportunity.
