GMT is a very powerful mapping and data visualization package. Generic Mapping Tools (GMT) is a set of open-source software for mapping and plotting geographic data. It features a command-line interface, which makes it completely different from the common GIS software like QGIS or ArcGIS.

An earthquake occurs due to a sudden release of energy in Earth’s lithosphere. Seismic waves are in fact, the vibrations that carry this energy from the source outwards in all directions.

Visualize the distribution and magnitude of earthquakes and explore their distribution at plate boundaries. Earthquakes are visualized on a 3D globe, making it easy to see their distribution within the Earth's surface.
