灵敏的微型气压计和地震仪在1980年5月18日圣海伦斯火山爆发的远处记录了强烈的大气声重力波。波的特征与大型核爆炸产生的波相似。独立的理论和经验分析表明，这次喷发的爆炸当量约为35兆吨。
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.
