Seismic Vulnerability Assessment of the Triumphal Arch of Caracalla in Volubilis (Morocco): Past Events and Provisions for the Future

A seismic vulnerability assessment of the Triumphal Arch of Caracalla in Volubilis, Morocco, reveals significant structural weaknesses despite its 1930s restoration. The arch, dating back to 216 AD, suffered severe damage during the 1755 Lisbon earthquake, which nearly destroyed it entirely. By analyzing historical drawings and archaeological evidence, researchers reconstructed the arch's original configuration and traced its seismic history. Using a rigid-block structural model, they assessed its current vulnerability to future earthquakes, providing critical insights for conservation efforts. This study highlights the long-term impact of seismic events on ancient structures and underscores the need for proactive measures to safeguard such heritage sites.
