产生地震的源
A hypocenter is the point where an explosion originates—either on the ground surface (for nuclear or meteor explosions) or below ground (for earthquakes). Understanding the hypocenter matters because it helps scientists and emergency responders locate where an event started and assess its characteristics and potential impact.

震源（英語：hypocenter），宏观上是指地震能量大量释放之处，而微观上是指首先发生地震波的地方，通常指地下岩层断裂错动的地区。在测震领域中，常将震源看作是一个理想化的面源或点源。其对应的震源深度——即震源垂直向上到地表的距离——也是最重要的地震基本参数之一。震级相同的地震，震源越深，影响范围越大，地表破坏越小；震源越浅，影响范围越小，地表破坏越大。一般地，使用米（m）或千米（km）作为震源深度的单位，用拉丁字母h作为符号表示震源深度。浅源地震的深度误差约为深度值的10%左右。震源愈深，相对误差愈小。
