飞行器利用机翼上下两面的压力差形成提升力以平稳的在空中飞行，而潜艇在原理上形同海下的热气球，通过调节自身浮力或升或降。

Aircraft use lift from their wings to stay aloft, while submarines operate like underwater balloons, adjusting their buoyancy to sink or rise.

这样一种在海下的延伸性地理结构引发了此次世界范围内最强烈的地震，与1960年智利9.5级地震和2004年苏门答腊9.1级地震强度接近。

That process of subduction triggers the largest earthquakes in the world, such as the magnitude-9.5 Chilean quake in 1960 and the magnitude-9.1 Sumatran quake in 2004.
