Abstract

Strong atmospheric acoustic-gravity waves were recorded by sensitive microbarographs and seismographs at large distances from the Mount St. Helens eruption of 18 May 1980. Wave signatures were similar to those of waves from large nuclear explosions. Independent theoretical and empirical analyses indicate that the explosive yield of the eruption was approximately 35 megatons.

摘要

强烈的大气声重波在距离 1980 年 5 月 18 日圣海伦斯火山爆发很远的地方，被灵敏的微气压计和地震仪记录下来。波的特征与来自大型核爆炸的波相似。独立的理论和经验分析表明，这次喷发的爆炸威力约为 3500 万吨。
