The term T waves is generally associated with acoustic waves generated by seismic events that subsequently travel horizontally in the ocean at the speed of sound. In this paper, we use a time-domain spectral-element method to perform a parametric study of the influence of seafloor slope, source position and media properties for a typical (downslope) T-wave generation scenario. We find that the energy and duration of these waves are particularly sensitive to the environment. In particular, the slopes and physical characteristics of the seabed play a crucial role for both the generation and the conversion of these waves. Likewise, the depth and position of the earthquake relative to the slope is of great importance, with the presence of privileged areas for the generation of T waves, which we map.

坡度、震源、海床和水柱特性对 T 波的影响：岸边生成

术语 T 波通常与地震事件产生的声波有关，这些声波随后以声速在海洋中水平传播。在本文中，我们使用时域谱元方法对典型（下坡）T 波生成场景的海底坡度、震源位置和介质属性的影响进行参数研究。我们发现这些波的能量和持续时间对环境特别敏感。特别是，海床的坡度和物理特性对这些波浪的产生和转换都起着至关重要的作用。同样，地震相对于斜坡的深度和位置非常重要，因为存在产生 T 波的特权区域，我们绘制了地图。
