Coeruptive and posteruptive crustal deformation associated with the 2018 Kusatsu-Shirane phreatic eruption based on PALSAR-2 time series analysis

Abstract Coeruptive deformation helps to interpret physical processes associated with volcanic eruptions.Because phreatic eruptions cause small, localized coeruptive deformation, we sometimes fail to identify plausible deformation signals.Satellite synthetic aperture radar (SAR) data allow us to identify extensive deformation fields with high spati

Risk Assessment System Based on Fuzzy Composite Evaluation and a Backpropagation Neural Network for a Shield Tunnel Crossing under a River

Constructing a shield tunnel that crosses under a river poses considerable safety risks, and risk assessment is essential for guaranteeing the safety of tunnel construction.This paper studies a risk assessment system for a shield tunnel crossing under a river.Risk identification is performed for the shield tunnel, and the risk factors and indicator
