• Resumen

  • Global Navigation Satellite System (GNSS) position time series are used pervasively in earthquake science to measure the surface response to earthquake cycle deformation. Characteristic usage cases are focused on the temporal windowing of position data to isolate coseismic, postseismic, or interseismic deformation. Here, we present an interactive visualization approach for the temporal evolution of GNSS time session in 2D in which the position estimates are amplified relative to their true positions, or are amplified relative to a reference state. This approach enables a rapid visual assessment of deformation patterns across all phases of the earthquake cycle in relation to topographic structure and active faults including azimuth reversal of coseismic and interseismic deformation.
