This repository contains data and post-processing analysis for a 2D numerical model of subduction. The focus of this analysis is to calculate the vertically integrated horizontal force balance.

LaTeX source for the article 'Correlations between the Topography-Induced Gravity, Terrain Structure and the Seismicity in the Gulf of Panama' (Lemenkova & Debeir, Environmental Research, Engineering and Management 2023, 79(2):64-76). GMT mapping of geoid, free-air gravity, topography and IRIS seismicity.

Over 35 GMT (Generic Mapping Tools) shell scripts producing regional geological and tectonic setting maps: relief basemaps overlaid with trenches, ridges, transform and fracture zones, ophiolites, volcanoes, LIPs, GSFML magnetic lineations, subducting-slab contours and plate-motion vectors, with fault/plate labels and legends.

Reproducible Python/PyGMT workflow testing the geomorphic imprint of subducting seamounts and ridges on Pacific trenches — axial-depth anomaly, inner-slope scarring and along-strike segmentation — from open bathymetry with statistics and a random-forest classifier.

GMT shell scripts for geophysical mapping of the Philippine Sea Basin: focal-mechanism beachballs (psmeca) from Global CMT and ISC catalogues, plate-velocity vectors (psvelo), geoid (EGM2008) and geology over GEBCO relief, with tectonic plate boundaries and trenches. Figures for Lemenkova, Romanian Reports in Physics 2022, 74(3):707.

GMT (Generic Mapping Tools) shell script drawing a global tectonic map: plate boundaries (PB2002) with rotation poles and boundary steps, GSFML seafloor fabric (fracture zones, magnetic lineation picks) and subducting-slab depth contours, on an Eckert IV equal-area projection centred on the Pacific.

GMT (Generic Mapping Tools) shell scripts for seismic and geophysical mapping of Ecuador: topography, geoid, free-air gravity and its gradient, and seismicity (earthquake epicentres), from GEBCO/SRTM, EGM2008 and earthquake catalogue data. Figures for Lemenkova, Geografie 2022, 127(3):195-218.

Interactive map of Earth's tectonic plates from real data — boundaries, earthquakes, volcanoes, cross-sections, and a 50 Myr reconstruction clock — plus PhET-style crust and plate-motion screens.
