Seismic microzones with morphological gradient QGIS 4 compatibility
QGIS 4 ready Active
Yes — Seismic microzones with morphological gradient supports QGIS 4 (declared max version 4.99.0).
This DTM-based plugin provides a critical territorial screening tool. By intersecting slope gradients (≥ 15°) with seismic microzonation data, it automatically identifies slopes prone to instability or motion amplification during earthquakes. An indispensable asset for geologists and land-use planners, it allows for rapid risk assessment, streamlined site investigations, and the design of targeted mitigation strategies, significantly reducing operational costs and time.
About
Seismic zones with morphological gradient (SMG). The morphological gradient in seismic areas with slopes greater than 15° can influence the propagation of seismic waves, amplifying their energy and increasing the risks of ground instability. This plugin identifies areas with a morphological gradient with slopes ≥15° within defined zones (input vector file) starting from the DTM.
