Scientists provide explanation for exceptional Tonga tsunami nature
Volcanoes can produce tsunamis through earthquakes, caldera and flank collapses, pyroclastic flows, or underwater explosions. These mechanisms rarely displace enough water to trigger transoceanic tsunamis. Violent volcanic explosions, however, can cause global tsunamisthat excite the atmosphere-ocean interface.
Here we use sea-level, atmospheric and satellite data from across the globe, along with numerical and analytical models, to demonstrate that this tsunami was driven by a constantly moving source in which the acoustic-gravity waves radiating from the eruption excite the ocean and transfer energy into it via resonance. A direct correlation between the tsunami and the acoustic-gravity waves’ arrival times confirms that these phenomena are closely linked.
