Exact excerpt

The January 15, 2022 Hunga eruption generated a complex tsunami. The tsunamis were likely generated by a combination of explosive eruptions and atmospheric pressure waves; small-scale flank collapse, radial pyroclastic density currents entering the water, and caldera collapse may also have contributed, but the timing and magnitude of these processes were still being evaluated.
