Massive volcanic eruption sent shockwaves into space: Scientists

Massive eruption of the underwater Tonga volcano in the South Pacific in January 2022 lofted material to heights exceeding 50 km and even sent shockwaves into space, a new study said. "Our recent investigation discovered the dramatic thermospheric responses at satellite altitudes," said scientists. Secondary gravity waves were responsible for the eruption rattling the skies, scientists explained.
