When an accidental explosion in a surface magazine is happened, the three primary events : air-blast, ground shock and debris, may be produced. To secure the surface structure and/or human life from these events, the magazine should be constructed in a subsurface. However, the hazard zones or safety distances for a subsurface magazine may be defined by the effects of air-blast and/or ground shock. In this study, to know the effects of air-blast pressure resulting from an accidental explosion in a subsurface magazine, explosion tests for small scaled specimens were done. In tests, the airblast pressure propagated to the surface was measured by the blast pressure sensors. This study is to examine the effects of blast pressure on a surface ground. From test results, it is found that the blast pressure from a subsurface magazine less than that from a surface magazine.
