Title: Clustering models for earthquake occurrences and extensions
Authors: Jiancang Zhuang - Institute of Statistical Mathematics (Japan) [presenting]
Abstract: The Epidemic-Type Aftershock Sequence (ETAS) model has become a de facto standard model, or null hypotheses, for testing other models and hypotheses related to seismicity. The purpose is to summarize the history of the ETAS model formulation and some other topics, including 1. Stochastic separation of earthquake clusters from the catalog; 2. Modelling the role of earthquake fault geometry in seismicity triggering and inversion of earthquake fault geometry based on seismicity; and 3. Incorporating depth and focal mechanism into the model formulation. The focus is on the methods of finding the features that are in the earthquake data but not described in the model. Such methods can also be applied to other point process models.
