| Abstract: | Slow earthquakes are one of the forms of earthquake energy releases. The study of the dynamics of slow earthquakes has become a frontier of contemporary research with great impact. This paper reviews the status of the international and domestic research of slow earthquakes, including the definition and main features of slow earthquakes, their characters in kinematics and dynamics, its identification and location, generation of slow earthquakes and their relations to geological settings, their physical mechanism of occurrence, numerical simulation of the complete process of slow earthquake occurrences, and so on. The paper also reviews the relations between long period precursors and slow earthquakes, as well as the relations between slow earthquakes and stress triggering and seismicity. The observation and investigation of slow earthquakes are not only important for theoretical studies on instability of the faults, but also provide a new approach in exploring the short and imminent earthquakes prediction. In China, the study of slow earthquakes is in a preliminary stage.It is believed that the immediate task is to show solid evidence to identify and locate some continental slow earthquakes and study their mechanism. For this purpose, it is critical to strengthen the network density and deploy seismometers,strainmeters, GPS and INSAR to cover entire frequencies of the crust deformation. At the same time, the comprehensive ability to analyze various data and simulate slow earthquakes should be reinforced. |
