Prevalence of Aseismic Slip Linking Fluid Injection to Natural and Anthropogenic Seismic Swarms

Anthropogenic fluid injections at depth induce seismicity which is generally organized as swarms, clustered in time and space, with moderate magnitudes. Earthquake swarms also occur various geological contexts such subduction zones, mountain ranges, volcanic, geothermal areas. While some similarities between anthropogenic natural have already been observed, whether they are driven by the same mechanism, or different factors, still an open question. Fluid pressure diffusion aseismic deformation processes often proposed to explain observations of hypocenters migration during while recent models suggest that swarm rather triggered fluid-induced fault slip. Here, using a global compilation 22 we observe duration, velocity, total moment scale similarly for all swarms. This supports common driving process both induced The scaling relations similar those found slow slip events. These highlight prevalence main driver earthquakes After quantifying released propose approach estimate seismic-to-total ratio, then compare theoretical estimation depends on velocity effective stress drop.
