Ionospheric disturbances from solar flares modeled as possible secondary triggers for large earthquakes
A team of scientists from Kyoto University has developed a capacitive-coupling model linking the ionosphere and Earth’s crust, showing that enhanced electron density during strong solar-flare activity could induce measurable electrostatic pressure inside fractured rock. The findings, published February 3, 2026, suggest space-weather disturbances may act as an additional stress factor when faults are critically loaded.
