Maybe interesting, I keep a list of large energy events/stores for thinking about the scale of global catastrophes.
Looks like this Tonga eruption is VEI5 or 6, so between St Helens and Pinatubo.
Comments appreciated in the doc!
- Mt. Toba 74kya, VEI 8/M8.8 eruption energy: 1e21-1e22 Joules
- M8 Volcanoes once every million years, but M7 yield > 10x more energy over time.
- Global Warming: 7.88e21 Joule/year
- Hiawatha Crater (Pleistocene, possibly 12kya) impact energy: 3e21 J
- Hurricane (1% kinetic, 99% latent heat): 1e21 J
- Human energy production 2013: 5.7e20 J/year
- Mt. Tambora 1815, VEI 7 eruption energy: 1.3e20 J
- Largest earthquakes 2: 1e19 J
- World nuclear weapon stockpile yield (extrapolated from USA): 16e18 J
- United States nuclear weapon stockpile yield 2020 (~2Gt TNT): 8.3e18
- Mt. Pinatubo 1991, Krakatoa 1883; VEI 6 eruption energy: 8.3e17 J
- Mt. St. Helens 1980, VEI 4 eruption energy: 1e17 J
