Table 2 Observational results at HKSi and predictions from the fault models

From: Estimation of fault models for short-term slow slip events from groundwater pressure in soft sedimentary layers

Data range (year/month/day) Observed Predicted
Groundwater level change (mm) Volumetric strain change (1e−8) Groundwater level change (mm) Volumetric strain change (1e−8)
2016/07/27-31 13.2 − 2.49 14.0 − 2.65
2016/12/15-17 7.5 − 1.41 1.5 − 0.29

  1. Observed volumetric strain changes were calculated from the observed groundwater level changes and crustal strain sensitivity (see Table 1). Predicted groundwater level changes were converted from the volumetric strain changes at HKSi predicted by the fault models and the observed crustal strain sensitivity
