The irregularity of the space-time distribution of earthquakes is one of the striking properties of both natural and man-made (induced) seismicity. The nature of spatial irregularities is usually associated with the structure of the environment - faults and other structural heterogeneities of the lithosphere. The nature of clustering in time is less intuitive because it must take into account the dynamics aspects of the fracturing process. An open question remains on the nature and the form of the relationship between spatial and temporal clustering. The study of earthquake clustering in natural seismicity has a long history, and recent advances in the analysis of induced seismicity and in laboratory experiments are now providing analogues across different scales and a wide range of better constrained conditions.
The goal of the Research Topic is to draw attention to the clustering property of seismicity at different scales and of different nature. Joint analysis of the results of laboratory modeling, observations of the real and induced seismicity and rock bursts in mines may provide a better understanding of this property, help find the fine line between coupled and independent seismic events, as well as define interaction mechanisms controlling seismic clustering. Study and comparison of the patterns of spatio-temporal clustering at different scales of space, time and energy are the subject of this Topic.
The scope of this Research Topic is to collect articles presenting original results and critical reviews in the following areas of research:
- Statistical studies identifying new properties and patterns of clustering of natural and man-made seismicity at different scales;
- Statistical studies quantifying the impact of various factors on the clustering of seismicity;
- Studies of clustering in induced and triggered seismicity;
- Laboratory research clarifying the physics of cluster formation and identifying factors that determine the statistical properties of clustering;
- Theoretical studies observations, clarifying the underlying physical processes and building models for clustering seismicity.
