DOI: 10.1007/s00024-022-03017-9
Abstract: The massive explosion by the January 15, 2022 Hunga Tonga-Hunga Ha’apai volcano in Tonga triggered a trans-oceanic tsunami generated by coupled ocean and atmospheric shock waves during the explosion. The tsunami reached first the coast… read more here.

DOI: 10.1029/2022gl099381
Abstract: Following the 15 January 2022 Hunga Tonga‐Hunga Ha'apai eruption, several trace gases measured by the Aura Microwave Limb Sounder (MLS) displayed anomalous stratospheric values. Trajectories and radiance simulations confirm that the H2O, SO2, and HCl… read more here.

DOI: 10.1029/2022gl100091
Abstract: On 15 January 2022, the submarine Hunga Tonga volcanic eruption lofted materials high into the upper stratosphere, reaching a record‐breaking altitude of ∼58 km, unprecedented in the satellite observations era. Within two weeks, the bulk… read more here.

DOI: 10.1029/2023gl102763
Abstract: Understanding the forces and magma system dynamics on timescales of seconds to minutes remains challenging. In the January 2022 phreatoplinian Hunga Tonga‐Hunga Ha'apai eruption, four remarkably similar seismic subevents within a 5‐min interval occurred during… read more here.

DOI: 10.1126/science.abo4364
Abstract: On 15 January 2022, the Hunga Tonga-Hunga Ha‘apai volcano erupted, producing tsunamis worldwide including first waves which arrived more than 2 hours earlier than what is expected for conventional tsunamis. We investigated the generation and… read more here.

DOI: 10.1126/science.abq2299
Abstract: Large volcanic eruptions, although rare events, can influence the chemistry and the dynamics of the stratosphere for several years after the eruption. Here we show that the eruption of the submarine volcano Hunga Tonga-Hunga Ha’apai… read more here.

DOI: 10.5194/os-19-517-2023
Abstract: Abstract. The eruption of the Hunga Tonga-Hunga Ha'apai volcano on 15 January 2022 provided a rare opportunity to understand global tsunami impacts of explosive volcanism and to evaluate future hazards, including dangers from “volcanic meteotsunamis” (VMTs) induced… read more here.
