文摘
- •
The impact of sea level changes is compared with present day fault slip tendency.
- •
Sea level changes can produce Coulomb stress changes of 0.5–1 MPa in Portugal.
- •
Faults with low slip tendency (Vilariça, LTV) are perturbed by sea level rise.
- •
Faults with high slip tendency (Horseshoe) are insensitive to ocean loading effects.
- •
Sea level rise may have triggered the paleo-earthquakes in the Vilariça fault.
