Performance Assessment of ISRO’S EOS-04 Interferometric SAR Data With USGS GPS for Geodetic Precision in Deformation Monitoring: a Case Study of Mauna loa volcano

In this paper, a comprehensive assessment of deformation using Interferometric Synthetic Aperture Radar (InSAR) data and Global Positioning System (GPS) measurements is carried out to achieve geodetic precision in monitoring volcanic activity. The study focuses on the Mauna Loa volcano in Hawaii, known for its dynamic deformation patterns. InSAR data acquired from EOS-04 satellite observations and GPS measurements from ground stations are analyzed to quantify surface deformation over a specified period. The results reveal spatial and temporal variations in deformation, highlighting areas of subsidence and upliftment across the volcano’s surface. Additionally, the study evaluates the accuracy and reliability of InSAR and GPS technologies in capturing deformation phenomena, demonstrating their complementary roles in geodetic monitoring. The findings contribute to a better understanding of volcanic processes and enhance our capability to assess volcanic hazards with greater precision.
