These data sets accompany the article "Forming a Mogi Doughnut in the years prior to and immediately before the 2014 M8.1 Iquique, Northern Chile earthquake" (Schurr et al., 2020).
The data sets consist of an earthquake catalog (2020-011_schurr-et-al_mogi_eqk_cat.txt) preceding the 2014 M8.1 Iquique, northern Chile earthquake, an inter-seismic locking model derived from GPS data for the northern Chile subduction zone (as plain text table and Generic Mapping Tools [GMT, Wessel et al. 2019] grid file: 2020-011_schurr-et-al_mogi_locking.txt and .grd) and the gravity field corrected for water column and subducted slab of the source region (GMT grid file: 2020-011_schurr-et-al_mogi_gravity). All data files are combined in one zip folder.
This dataset presented herein originates from the JAGUARS (The Japanese German Underground Acoustic Emission Research in South Africa) project, which took place from 2007 to 2009 in Mponeng Gold Mine, South Africa. Project partners included Ritsumeikan University, Earthquake Research Institute University of Tokyo and Tohuku University in Japan, the German Research Center for Geosciences Potsdam and Gesellschaft für Materialprüfung und Geophysik GMuG mbH in Germany, as well as the Council for Scientific and Industrial Research in Johannesburg, Seismogen CC in Cartonville, Anglo Gold Ashanti Ltd and the Institute of Mining Seismology in the Republic of South Africa. This publication forms part of the Geo-INQUIRE initiative (HORIZON-INFRA-2021-SERV-01 call, project number 101058518).
It is cross-referenced on the EPISODES Platform (https://episodesplatform.eu/?lang=en#episode:JAGUARS (not yet existing)), which is managed by the EPOS TCS AH (European Plate Observing System Thematic Core Service Anthropogenic Hazards). Within the EPISODES Platform, the datasets are consolidated into an “episode” titled “JAGUARS: Mining induced picoseismicity associated with gold mining”. The EPISODES Platform offers open access to the integrated research infrastructures of the EPOS TCS AH, enabling users to download data and utilize a range of basic online visualization tools to graphically represent and process the datasets directly within their personal workspace.
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).
