[SSS06-06] 情報理論に基づく地震予測可能性の定量化およびETASモデルの予測能力
キーワード:地震予測、地震可予測性、ETAS、統計地震学
In earthquake forecasting, there is a significant gap between complete randomness and complete deterministicity. This presentation begins by discussing how to quantify predictability from an information-theoretic perspective. In particular, the difference in system entropy between a forecasting model and the model of complete randomness is used as a standard measure of predictive capacity. The presentation then examines the predictive capacity of the ETAS model and concludes with an overview of the current state of earthquake predictability, discussing potential improvements to existing earthquake forecasting models.
