80 Years After the Earthquake, Onesvie Calls for Strengthening Construction Standards in the Dominican Republic

Aug 5, 2026, 12:05 PM

On August 4, the Dominican Republic commemorates the 80th anniversary of the devastating earthquake that struck its northeastern coast in 1946. In light of this significant event, the National Office of Seismic Evaluation and Infrastructure Vulnerability (Onesvie) has issued a call to action for both the public and private sectors to enhance compliance with seismic-resistant construction standards.

The earthquake, which reached a magnitude of 8.1, not only caused severe human and material losses but also serves as a poignant reminder of the importance of preparedness and infrastructure resilience.

Historical Context of the 1946 Earthquake

The earthquake that struck on August 4, 1946, is one of the most significant natural disasters in the history of the Dominican Republic. With a magnitude of 8.1, it not only caused a catastrophic loss of life but also triggered a tsunami with waves reaching approximately 16 feet high. The aftermath saw extensive damage to infrastructure, marking a pivotal moment in the nation’s approach to disaster preparedness and building resilience.

In its wake, the Dominican Republic faced a long recovery process, which highlighted the need for stringent building codes and regulations to safeguard against future seismic events. This historical event serves as a critical reminder of the vulnerabilities inherent in the country’s infrastructure.

Current State of Construction Standards

As the anniversary of the earthquake approaches, Onesvie's director, Leonardo de Jesús Reyes Madera, emphasizes the urgent need to strengthen compliance with seismic-resistant construction standards. He pointed out that the responsibility for ensuring these standards is a shared one, involving both public and private sectors. The current construction practices must be scrutinized to prevent unsafe building methods that stem from the misconception that a major seismic event will not occur again.

Reyes Madera advocates for a comprehensive evaluation of strategic buildings and infrastructures, including schools, hospitals, and essential services, to identify vulnerabilities and enhance their resilience. This proactive approach is crucial for safeguarding lives and minimizing economic and social impacts in the event of a significant earthquake.

The Path Forward: Building Resilience

Reyes Madera concludes with a strong message about the importance of investing in structural vulnerability reduction. He argues that such investments are not merely expenditures but essential measures that protect lives and reduce the potential economic and social impacts of a major earthquake. The seismic code must ensure that buildings not only protect occupants but also remain functional after a seismic event, particularly those that provide essential services.

Furthermore, he urges the public to cultivate a culture of prevention and adherence to construction norms, emphasizing that respect for life is built through prevention and rigorous application of seismic-resistant standards. As the Dominican Republic reflects on its past, it must also prepare for a safer future.
