Advanced Geophysical Observations, Analytical Methods, and New Insights for Earthquake Swarms
Earthquake swarms are clusters of earthquakes that are localized in space and time but do not have a distinctive mainshock or a temporal decay of event rates characteristic of aftershocks. Earthquake swarms can trigger large, damaging earthquakes; however, their causality is not yet clear. In the last decade, there has been a remarkable surge in geophysical observations, such as dense seismic arrays, distributed acoustic sensing (DAS), borehole strainmeters, Global Navigation Satellite System (GNSS), and Interferometric Synthetic Aperture Radar (InSAR). This wealth of geophysical data provides an unprecedented opportunity to improve our understanding of the processes governing earthquake swarms and their hazards across various temporal and spatial scales, including tectonic, structural, geothermal, and anthropogenic conditions. Advances in the development of computing algorithms provide new opportunities to further probe earthquake sequence evolution within complex fault systems and to link these processes with improved observations.
The aim of this session is to explore innovative geophysical methodologies to observe and analyze earthquake swarms and to illuminate fresh perspectives on the underlying physics. We welcome contributions that encompass a wide range of topics, including but not limited to:
- novel algorithms for constructing earthquake catalogs, incorporating state-of-the-art artificial intelligence tools,
- advanced geospatial and statistical analyses and simulations of observed swarms,
- hazard applications using seismology and other complementary geophysical data such as GNSS and InSAR.
