Which consequence develops in Inca dry stone masonry when seismic resonance increases?

A)Stresses exceed frictional resistance
B)Mortar degradation lowers tensile strength
C)Settlement increases material density
D)Efflorescence accelerates chemical weathering

💡 Explanation

In dry stone masonry, seismic resonance amplifies vibrational forces; because interlock dictates stability exceeding static friction causes joint slippage. Therefore, collapse risk increases, rather than consolidation by settlement or chemical weathering that presupposes a binding matrix.
