Summary:
- The article analyzes the 2022 Hunga Tonga-Hunga Haʻapai volcanic eruption, which produced an atmospheric shockwave that triggered a global tsunami, challenging previous geological models.
- Researchers identified that the eruption's unique interaction between the volcano's caldera and the ocean created a "meteotsunami" effect, where atmospheric pressure waves coupled with sea-level displacement to amplify wave height and speed across the Pacific.
