Enhanced earthquake catalog (2017–February 5, 2023) for the epicentral region of the 2023 Mw 7.8 Kahramanmaraş earthquake, Türkiye

This earthquake catalog was constructed using a combination of artificial intelligence and traditional methods for phase picking, phase association, and earthquake relocation. It covers the period from January 1, 2017, to February 5, 2023—one day prior to the Mw 7.8 earthquake that struck Türkiye.

The dataset includes three subsets:

1) Raw Catalog: Comprises 14,128 events obtained from the full association and relocation process, without filtering based on event type or location quality.

2) Earthquake Catalog: Comprises 5,721 tectonic events with well-constrained hypocenters (68% confidence ellipsoid semi-major axis < 8 km and depth < 15 km).

3) Anthropogenic Catalog: Comprises 1,695 human-induced events, primarily quarry blasts, also with well-constrained hypocenters (68% confidence ellipsoid semi-major axis < 8 km and depth < 15 km).
