G-DIP is a compilation of 597 uniquely determined fault plane dip angles corresponding to 269 individual earthquakes. It includes two main types of dip determinations: one based on the Global Centroid-Moment-Tensor Project (https://www.globalcmt.org/), the CMT collection, with 253 dip determinations of the activated nodal plane, and the other based on studies that used various techniques, the FLT collection, with 229 fault dip determinations. The FLT collection includes 525 cases of multiple determinations for the same earthquake. The paired determinations, i.e., earthquakes for which the CMT solution and at least one FLT solution exist, are 221. All determinations are classified depending on faulting categories as normal, reverse, transcurrent crustal faulting, and subduction-interface reverse faulting. Most of these earthquakes are located near plate boundaries; 63 are reverse faulting events identified as having occurred on subduction interfaces, 184 occurred in the continental crust, and 18 in the oceanic crust. Four subduction interface earthquakes were discarded because their faulting mechanism is inconsistent with reverse faulting. Among all the 202 crustal earthquakes, 68 events are located at a distance greater than 300 km from the plate boundaries. Several of these earthquakes that occurred in the plate interiors are located very far away from plate margins, such as those in the North American, Australian, and Asian continental interiors; one of them is in the middle of the Pacific plate. The transcurrent faulting earthquakes include both oceanic transforms and continental strike-slip faults. None of the normal faulting earthquakes belong to oceanic spreading ridges because of the lack of univocal fault plane determinations in that specific tectonic setting. Earthquakes classified as intraslab are not included.
