This is obviously a concern when the protection of citizens is concerned. There are some indications that both the topography and weather conditions may play a significant role but this remains rather qualitative and there is a need to clarify such points. In this paper, the results of a preliminary experimental campaign are presented in which up to 500 kg eq TNT was detonated in the open atmosphere and the pressure field measured up to 10 kms. %G English %2 https://ineris.hal.science/ineris-01855088/document %2 https://ineris.hal.science/ineris-01855088/file/2015-207%20post-print.pdf %L ineris-01855088 %U https://ineris.hal.science/ineris-01855088 %~ SDE %~ INERIS %~ GIP-BE
