Abstract
On 15 January 2022 the Hunga Tonga-Hunga Ha’apai underwater volcano erupted. The eruption (ML5.8) generated pressure and surface waves that travelled across the globe. Figure 1 is the satellite imagery at the time of the eruption showing the scale of the blast. The eruption generated an atmospheric pressure wave that wrapped around the earth multiple times and was detected globally at atmospheric pressure gauges (Lynett, 2022). A tsunami was also generated at the volcano itself via some combination of the explosion and mass movements.References
