Quantifying the 1D explainability of low-variability and poor-misfit site responses via S-wave velocity inversion for site amplification factors

One-dimensional site response analysis is widely used in seismic hazard assessment, but its explanatory capability is often considered to be limited when we have sites where existing velocity structures cannot reproduce the observed amplification characteristics. This study quantitatively evaluates the extent to which...

Nanoscale fracture mechanisms in defective α‐ quartz induced by compression: Insights from molecular dynamics simulation

Clarifying the fracture mechanisms at the nanoscale is essential for constructing a multiscale framework of rock fracture. In this study, molecular dynamics simulation is employed to investigate the fracture behavior and associated strength evolution in defective α ‐quartz containing either a single hole or doubl...
