The Parkfield prediction fallacy
James C. Savage
1993, Bulletin of the Seismological Society of America (83) 1-6
The Parkfield earthquake prediction is generally stated as a 95% probability that the next moderate earthquake there should occur before January 1993. That time limit is based on a two-sided 95% confidence interval. Because at the time of the prediction (1985) it was already clear that the earthquake had not...
