It is not from lack of trying. Geophysicists have been trying for 50 years. There was a glimmer of hope when I started grad school with Russians promoting pre-quake velocity anomalies and radon emissions anomalies. And Chinese promoting animal behavior. Neither were reproducible or reliable after extensive study.

Then prediction research became the black death of academic careers with little progress.

This century a milder version called 'earthquake forecasting' has gained acceptance. That is more big data and statistical odds.

Plus 'early warning' seeks to detect quakes and warn people at the speed of light, seconds before damaging waves arrive at the speed of sound.
