Summary

Story summary

A Kyoto University study proposes solar flares may indirectly influence earthquakes.
They say electron density changes during solar events could create electrostatic forces.
These forces could affect already stressed faults, the researchers contend.
They cite the 2024 Noto Peninsula earthquake in Japan as a potential example.
Critics argue the model is simplistic, and more research is needed to validate it.
