摘　　要：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].
