"Earthquakes and Volcanos
As a further complication in a Grand Solar Minimum, cosmic rays that make it to Earth and enter the surface, can trigger earthquakes and volcanoes and other tectonic anomalies. The penetrating particles (cosmic ray muons) from space decrease the viscosity of silica-rich magma. See: “Explosive volcanic eruptions triggered by cosmic rays: Volcano as a bubble chamber.”
