**2. Conclusions**

The eight papers published in this collection represent a non-exhaustive list of the most recent leading topics in the fields of statistical seismology and pattern recognition applied to the spatiotemporal evolution of seismicity. Given the complexity of the topic, a rigorous methodology to the approach to the study of spatiotemporal properties of seismicity is needed. Descriptions of methods and implementations of modern and advanced methodologies from multidisciplinary approaches are needed for a shared understanding of the topic and as a starting point for new research. Therefore, this collection stands as an important starting point to outline the issues of interest as well as new challenges in this field.
