The submarine volcano eruption of Hunga Tonga-Hunga Ha’apai that occurred on January 15, 2022, generated impulsive downward reaction forces on Earth, radiating seismic waves throughout the planet. Geologists analyzed the teleseismic waves and Rayleigh waves at approximately 50 seconds to determine the force history and provide insights into the overall volcanic eruption process. The acoustic waves generated during the process produced broadband ground motions across the land alongside conventional tsunami waves.
