hartografía

Hartografía, also referred to as stonewall or block mapping, is a cartographic technique used to display convergent movements, such as those observed in the Earth's crust and upper mantle, by using different colors to represent various types of tectonic features. This method originated in the early 20th century among seismologists and geodynamics researchers to depict earthquake-induced deformation and strain accumulation in the Earth's crust.

In a harteograph, hypothetical walls or barriers separate areas of the map, where each zone represents a different type of tectonic deformation. The method allows for the visualization of convergent and divergent structures, faults, and sheared zones within the Earth's crust. By combining data from earthquakes, deformation measurements, and observational seismology, seismologists can employ various tectonic models to interpret the datagram of the harteograph.

The primary goal of harteography is to generate graphs and models that might illustrate the deformation in the Earth's crust. To construct such a graph, a net of datagrams is aligned on grid maps. Both the location of ruptured areas and deformation periods obtained using geodesy are used to prepare horograms, and long transformation is created to break different observations with each deformation datagram.

In practice, the visualization method of harteography uses different colors to distinguish tectonic structures. Blue represents contraction, green represents pure distortion, and yellow represents extensive shearing areas.
