The Coulomb stress theory is the basic physics principle upon which scientists rely for improving our understanding behind earthquake triggering processes and, therefore, our predictability of future earthquake hazards. The assumption that following a large earthquake the expected regional stress redistribution will affect other faults has been known since the late nineteenth century and has been passed on for further consideration by Charles Richter. However, we still struggle to define its implementation principles in short‐term forecasts. This opinion article discusses the recent advances in physics‐based earthquake forecasting to motivate an open discussion about what we have collectively learnt from the...
