摘要

2022年1月15日，Hunga Tonga-Hunga Ha 'apai火山(HHTH)在04:14:45UT开始喷发。海底HTHH火山喷出的火山灰高达33-35公里，并产生了巨大的大气冲击波，传播到世界各地。这一事件似乎引发了两场海啸:一场是由水下喷发引起的，另一场是由大气冲击引发的，其传播速度比普通海啸快，震级也更大。冲击波和海啸波到达电离层[例1、2、3]。

How the 15 January 2022 Hunga Tonga- Hunga Ha’pai volcano eruption shook the ionosphere

On January 15, 2022, the Hunga Tonga-Hunga Ha’apai (HHTH) volcano began to erupt at 04:14:45UT. The submarine HTHH volcano sent a plume of ash that reached as high as 33-35 km of altitude and generated a giant atmospheric shock wave that propagated around the world. The event seemed to generate two tsunamis: the one was generated by the underwater eruption and the other was triggered by the atmospheric shock that propagated faster than normal tsunami and was of larger magnitude. The shock waves and tsunami waves reached the ionosphere [e.g., 1 , 2 , 3 ].
