例句 Examples

The hypocenter of the earthquake was located 15 kilometers below the surface.
这次地震的震源位于地表以下15公里处。

By analyzing seismic waves recorded at multiple stations, scientists were able to pinpoint the hypocenter with remarkable precision, revealing a previously unknown fault line.
通过分析多个监测站记录到的地震波,科学家们得以极为精确地定位震源,从而揭示了一条此前未知的断层线。

词源 Etymology

该词由希腊语前缀 hypo-(意为"在……之下")与 center(中心)组合而成。hypo- 在科学术语中常表示"下方、低于",如 hypothermia(体温过低)、hypodermic(皮下的)。Hypocenter 字面意思即"位于下方的中心点",形象地描述了地震能量从地下深处释放的起始位置。该词在20世纪地震学发展过程中被广泛采用,后来也被用于描述核爆炸的爆心投影点。
