As a new spatial observation technology，the remote sensing technology has been applied in various fields. This paper deals with some application results of remote sensing technology in the earthquake science，such as active fault detection，Earth crust deformation，thermal anomaly and seismic hazard evaluation. In recent years，electromagnetic satellites devoted to earthquake research were launched successfully in some countries，e.g.，Russia and France，which yielded quite abundant electromagnetic information relating to the earthquake in the ionosphere. These data are called non-imaging remote sensing information. More and more earthquake scientists have believed that such information is of great significance to earthquake electromagnetic science study and earthquake short-term prediction. Remote sense technology（imaging and non-imaging）used in the earthquake field will heighten China's capability for earthquake monitoring and forecasting.
