We show the equivalence of earthquake‐induced ground acceleration and water‐pressure waveforms for the case of collocated hydrophones and seafloor seismometers installed in shallow water. In particular, the comparison of the waveforms and amplitude spectra of the acceleration and water‐pressure signals confirms the existence of a frequency range of “forced oscillations” in which the water‐pressure variations are proportional to the vertical component of the ground acceleration. We demonstrate the equivalence of the acceleration and water‐pressure signals for a set of local earthquakes (epicenter distance of a few tens of kilometers) and regional earthquakes with a wide range of magnitude (⁠2.7

当水听器用作加速度计时

对于在浅水中安装的并置水听器和海底地震仪，我们展示了地震引起的地面加速度和水压波形的等效性。特别是，加速度和水压信号的波形和振幅谱的比较证实了存在“强迫振荡”的频率范围，其中水压变化与地面加速度的垂直分量成比例。我们证明了一系列局部地震（中心距几十公里）和大范围地震（2.7）的加速度和水压信号的等效性。
