The eruption from the Hunga-Tonga volcano in Tonga on January 15th was enormous, causing a tsunami across the Pacific, an ash cloud that extended 20km into the atmosphere, and an overpressure wave that went around the world. This video examines the impact of the eruption on the atmosphere, and explains why it seems to have caused a world-first observation of a volcanically induced meteotsunami.

Note that many of the figures in this video have come from volcanologists and geologists on Twitter - they are doing amazing, rapid data visualisation and deserve a follow!

Looking why the Tongan eruption on January 15th was so unique, the impact of the Tonga eruption on the atmosphere, the Pacific tsunami from the Tongan volcano, and the unprecedented meteotsunami that was detected in the Pacific and Caribbean. Really this video is about ocean-atmosphere dynamics, and how the planetary fluids of the Earth's atmosphere and oceans can interact to produce amazing results. If you like videos from Smarter Every Day, Veritasium, PBS Eons, Crash Course, or Sci Show you will enjoy this interesting video about the Tonga eruption and tsunami.
