GNSS, leveling, and InSAR are powerful tools for monitoring crustal movements associated with earthquakes, tectonic loading, creeping of active faults, and other geological processes such as landslides, volcanoes, and land subsidence. In active regions like Taiwan and Japan, crustal deformation has been closely monitored using dense permanent GNSS arrays, repeated leveling, and additional techniques such as GNSS/Acoustic measurements. This abundance of geodetic data allows for a comprehensive evaluation of the potential for various geological disasters. For example, geodetic data can provide independent seismic hazard information, complementing geological and seismological data. However, the accuracy of these estimations heavily depends on the methodologies and assumptions used. The geodetic approach to seismic hazard analysis is an evolving field, with ongoing developments aimed at improving reliability and precision. In this special issue, we welcome submissions on studies that focus on geodetic data analysis and the estimation of seismic and other geological disaster potentials in active regions across Taiwan, Japan, Indonesia, Philippines, and other areas. We particularly encourage research that advances the current understanding and application of geodetic techniques in hazard assessment.
Topics of interest in this collection include, but are not limited to:
- Case studies of earthquake potentials, seismic hazards and other geological disasters based on the geodetic observations
- Analysis methods for assessment of earthquake potential, seismic hazards and other geological disasters
- Improvement of GNSS observations, leveling measurements, InSAR, and imaging geodesy for crustal deformation analysis
- Crustal deformation modeling based on the geodetic observations
- Quantification of activity levels of crustal deformation for geological disaster assessment
