Volcanic Tsunami and Its Prediction for Early Warning
Description:
Volcanic tsunamis pose serious threats to nearby coastal communities. Our study of the 2022 Tonga volcanic event revealed that the erupted air-pressure wave was a precursor to the tsunami. Contrary to previous theories, our findings indicate that the eruption process drives both the air-pressure wave and tsunami dynamics through a coupled atmosphere-ocean source mechanism. This insight offers a new approach for incorporating air-pressure sensors into early warning systems.
