TL;DR: In the Kingdom of Tonga, the Hunga volcano experienced an 11-h long violent eruption which generated a significant near-field tsunami as discussed by the authors , reaching a peak height of 19 m in western Tongatapu, 20 m on south-eastern Nomuka Iki island, and 20m on southern Tofua, located approximately 65 km S and E and 90 km N from Hunga.

Numerical simulations of water waves generated by subaerial granular and solid-block landslides: Validation, comparison, and predictive equations
TL;DR: In this paper , the authors compare the maximum initial wave amplitude and slope angle for both solid-block and granular landslides and propose equations for predicting the maximum wave amplitudes.

A new dual earthquake and submarine landslide source model for the 28 September 2018 Palu (Sulawesi), Indonesia tsunami
TL;DR: In this paper , the authors proposed a dual source model including a submarine landslide, which is based on the results of a marine bathymetric survey, which identified evidence for submarine landslides within the Palu Bay.

TL;DR: A tsunami simulation of the Tongan Archipelago calibrated by field observations, drone, and satellite data is presented in this paper . But the authors focus on the Hunga Tonga-Hunga Ha'apai (HTHH) volcanic eruption in January 2022, which generated catastrophic tsunami and contends for the largest natural explosion in more than a century.
