Title: Earthquake as a complex phenomenon: Some recent developments about earthquake occurrence, modelling and forecasting

Abstract
Earthquakes are complex phenomena that result from the coupled interaction of several fundamental physical and chemical processes. Till now, earthquake forecast is still a very difficult scientific problem because earthquake process covers a vast range of spatial- and temporal scales, a lot of non-linear process are involved, and boundary and initial conditions are difficult to determine. I am going to talk about some basic observational facts about earthquakes, such as earthquake size distribution and aftershock distribution. Some recent theoretical approaches and forecast methods about earthquake occurrence and forecast such as stress triggering, Self-Organized Critical models, Accelerating Energy Release and Load/Unload Response Ratio are also going to be discussed.
