Macedonio, G. and Costa, A. (2012) Brief communication. Rain effect on the load of tephra deposits. Natural Hazards and Earth System Science, 12 (4). pp. 1229-1233. ISSN 1684-9981 doi: 10.5194/nhess-12-1229-2012

Abstract/Summary

Accumulation of tephra fallout produced during explosive eruptions can cause roof collapses in areas near the volcano, when the weight of the deposit exceeds some threshold value that depends on the quality of buildings. The additional loading of water that remains trapped in the tephra deposits due to rainfall can contribute to increasing the loading of the deposits on the roofs. Here we propose a simple approach to estimate an upper bound for the contribution of rain to the load of pyroclastic deposits that is useful for hazard assessment purposes. As case study we present an application of the method in the area of Naples, Italy, for a reference eruption from Vesuvius volcano.
