We know very little about the processes that lead to a re-eruption of supervolcanoes, such as the mostly underwater Kikai caldera in Japan, and are therefore ill-equipped to make predictions. Credit: Seama Nobukazu

Illustration of the dynamo mechanism that generates the Earth's magnetic field: convection currents of fluid metal in the Earth's outer core, driven by heat flow from the inner core, organized into rolls by the Coriolis force, generate circulating electric currents, which supports the magnetic field.
