Tongan Eruption

In January 2022, the Hunga Tonga-Hunga Ha’apai volcano erupted spectacularly, sending waves around the world through the air, water, and ground. In many ways, it was unlike any eruption scientists have observed, though they think it bears similarities to the 1883 eruption at Krakatoa. This video summarizes some of the research to come out of the eruption, looking at how waves propagated, what aerosols the volcano pushed high into the atmosphere, and what the long-term effects of the eruption may be.
