Abstract
Earthquakes and slow-slip events interact, however, detailed studies investigating their interplay are still limited. We generate the highest resolution microseismicity catalog to date for the northern Armutlu Peninsula in a ∼1-year period to perform a detailed seismicity distribution analysis and correlate the results with a local, geodetically observed slow-slip transient within the same period. Seismicity shows a transition of cluster-type behavior from swarm-like to burst-like, accompanied by an increasing relative proportion of clustered (non-Poissonian) relative to background (Poissonian) seismicity and gradually decreasing b-value as the geodetically observed slow-slip transient ends. The observed slow-slip transient decay correlates with gradually increasing effective-stress-drop values. The observed correlation between the b-value and geodetic transient highlights the influence of aseismic deformation on seismic deformation and the impact of slow-slip transients on local seismic hazard.
