The enhanced catalog is constructed using template events from the STA/LTA relocated catalog of Martínez-Garzón et al. (2022, https://doi.org/10.5880/GFZ.4.2.2021.004).

It is built using waveforms and phase arrivals from up to 30 stations of the SMARTnet temporary seismic network, two stations of the GONAF borehole permanent network, and three stations of the KOERI permanent network for channels that contain data for at least the 80% of the day. The magnitudes of the new detections are calculated by relative amplitude difference with the respective template. The magnitude of completeness of this catalog is Mw = 0.8. The catalog spans the time period from 25 January 2019 to 07 February 2020. Direct evidence of a slow-slip transient modulating the spatiotemporal and frequency-magnitude earthquake distribution: insights from the Armutlu Peninsula, northwestern Turkey" by Bocchini et al. (2022).

The dataset consists of two files:
(1) “enhanced_catalog_absolute_locations.csv” that contains 7,677 seismic events (templates and new detections) for which we could successfully calculate an earthquake location; and
(2) “enhanced_catalog_relocated.csv” that contains 4,128 seismic events for which we could refine the initial location and obtain a double-difference refined location.
