<正>On 15 January 2022, the Hunga Tonga-Hunga Ha’apai volcano(20.54°S 175.39°W), a submarine volcano located about 65 km north of Tonga’s main island in the South Pacific, violently erupted with a powerful explosion [1]. The volcanic explosivity index (VEI)was estimated to be 6 indicating that the eruption was among the largest volcanic activity ever observed with modern geophysical instrumentation [2]. The explosion ejected an enormous ash plume to record-breaking heights of～55 km [3] and caused atmospheric waves that propagated across the globe in less than 24 h [4].
