Tongo facts Tsunami in 2022 (5)
A
- The Hunga Tonga-Hunga Ha’apai volcano had an eruption in January of 2022, forming an initial wave which was around 90 metres high while releasing more energy than the most powerful nuclear bomb ever detonated.
- known to cause electric currents in space.
- underwater volcano caused a wave around nine times taller than that from the highly destructive 2011 Japan tsunami.
- monitoring did not detect initial wave as it was programmed to detect underwater waves rather than atmospheric waves as it cost more ( 30 yrs behind )
- ## killed 5 ppl
