Alert and careful we can do but being clever in volcanology involves complexities that are unfathomable. We can know historic frequencies of eruptions and a few earthquakes from tsunami evidence but we do not know the breaking point of quadrillions of tons of subterranean rock features or even the actual forces on rock structures. |
