The new study builds on previous research, which revealed that the eruption resulted in the highest ash plume ever recorded, reaching a height of 57 km (35 miles).
Guardian reports that the eruption sent ash and debris 20 km into the air. Previously, it was believed that the volcanic eruption caused a tsunami that hit several islands, with waves reaching as high as 15 metres. However, a computer simulation of the event suggests that the western coast of Tofua Island experienced waves as tall as 45 metres in height.

Dr Mohammad Heidarzadeh from the University of Bath, who has previously conducted research on the Tonga volcano eruption, has commented on a new study. He notedthat the study benefits from a diverse observation dataset, which has enabled the researchers to create the most detailed modelling of the tsunami to date. He also remarkedthat the results of the study are consistent with his ownresearch, which suggested that the maximum tsunami wave height was 90 metres.
"Modelling tsunamis from volcano eruptions is a challenging task and this has been nicely done," he said, as quoted by the Guardian. "It is interesting that the results are consistent with our previous study on this event, where we reported a maximum tsunami wave height of 90 metres," he added.
