Which risk increases when constructing Roman fortifications using opus caementicium in regions prone to seismic activity?

💡 Explanation

Reduced structural integrity over time increases, using opus caementicium, because seismic activity induces dynamic loading causing internal fracturing of concrete via stress propagation; therefore, the wall’s resistance weakens rather than other costs increasing or projectile defense improving.
