NEW: Researchers discover the Hunga Tonga-Hunga Ha’apai volcano triggered atmospheric gravity waves that reached the edge of space. The waves reverberated around the planet at least six times and reached close to their theoretical maximum speeds – at 320m per second or 720mph. The study also confirmed the eruption of the Hunga Tonga-Hunga Ha’apai submarine volcano in January 2022 was one of the most explosive volcanic events of the modern era.
