Could ionospheric disturbances influence earthquakes?

Researchers at Kyoto University have proposed a new physical model that explores how disturbances in the ionosphere may exert electrostatic forces within Earth's crust and potentially contribute to the initiation of large earthquakes under specific conditions. The study does not aim to predict earthquakes but rather presents a theoretical mechanism describing how ionospheric charge variations—caused by intense solar activity such as solar flares—could interact with pre-existing fragile structures in Earth's crust and influence fracture processes.
