Which condition leads to increased risk when lime mortar joints exist between Inca masonry blocks?

💡 Explanation

Seismic displacement creates shear forces that can overcome mortar cohesion, leading to joint failure via frictional sliding because the tensile strength of quicklime mortar is lower than that of rock. Therefore, differential movement risks structural damage, rather than thermal stress issues.
