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.
We present a 3-D lithospheric-scale data-constrained structural model covering the area of North Patagonian Massif Plateau (NPM) and its surroundings. These data are supplementary material to “Lithospheric 3D gravity modelling using upper-mantle density constraints: Towards a characterization of the crustal configuration in the North Patagonian Massif area, Argentina” (Gómez Dacal et al. 2017).
The North Patagonian Massif (NPM), in central Argentina, includes a plateau of an average altitude of 1200 m.a.s.l. mostly surrounded by basins that stand between 500 to 700 m below it. Geological observations and previous works indicate that the present-day elevation of the plateau was reached in the Paleogene by a sudden uplift that did not involve noticeable deformation. To gain insight into the causes of the uplift and the geodynamic development of the area, it is necessary to characterize the present-day configuration of the lithosphere.
The Northeast Atlantic (NEA) region has long been a subject of interest due to its complex geological history, particularly regarding the interaction between the Iceland plume and the lithospheric plates. In this data publication, we present a comprehensive three-dimensional structural and density model of the NEA crust and uppermost mantle, consolidating and integrating a wide range of previously fragmented data sets. Our model highlights the influence of the Iceland plume on the region's geological evolution, shedding light on the mechanisms that facilitated the continental breakup between Europe and Laurentia during the earliest Eocene period. The whole workflow and methods are described in Gomez Dacal et al. (2023) and its Supplementary Information.
