Which outcome occurs when Roman aqueduct arches experience excessive lateral thrust?

💡 Explanation

In Roman aqueducts, excessive lateral thrust from earthquakes can cause voussoir keystone displacement because the arch's geometry is compromised, and keystone supports vanish. Therefore, arches fail, rather than mortar weakening or chemical changes, which are slower degradation mechanisms.
