Operation Ceniza-Arena: Techniques for the Measurement of Deposition and Redistribution of Fallout Around Structures

Abstract

The continuing eruptions of Volcan Irazu and the consequent deposition of volcanic debris on the city of San Jose, Costa Rica, offered a unique opportunity to improve our understanding of deposition and redistribution of fallout-like particles (ceniza-arena) around structures. The techniques for the measurement of the deposition and redistribution of fallout were proof-tested and evaluated during the series of field measurements. The results were limited by the lack of volcanic activity during the measurement periods; however, the measurements showed a possible relationship between wind speed and the mass of fallout deposited.
