This book presents 10 specific actions to be undertaken in order to provide results of practical relevance in seismology. From the statistical analysis of earthquakes, we can estimate the earthquake mean recurrence time and the probability of occurrence of the next earthquake. In addition, through statistical analysis, we can identify correlated foreshocks and estimate the occurrence time of the main shock. As the book shows, the general state of seismicity of a given seismic region can be assessed by statistical means, in particular the earthquake entropy. From measurements of the seismic waves on the Earth's surface, we can deduce the tensor of the seismic moment, the earthquake's energy and magnitude, as well as the orientation of the fault, the fault slip, the focal volume and the duration of the seismic activity.
