2010s Caribbean earthquake sequence The 2010s Caribbean earthquake sequence was a multi-year series of seismic events that affected the Greater Antilles, Lesser Antilles, Cayman Islands, Puerto Rico, Hispaniola, Jamaica, and adjacent offshore regions between 2010 and 2019. The sequence involved interactions among the North American Plate, Caribbean Plate, Gonâve Microplate, and South American Plate, producing notable earthquakes, aftershocks, tsunami threats, and crustal deformation documented by international agencies and academic institutions. The series influenced policy and research at organizations such as the United States Geological Survey, Caribbean Disaster Emergency Management Agency, and various universities.

Background and tectonic setting

The Caribbean region lies at the complex boundary of the North American Plate, Caribbean Plate, and South American Plate, with subplates including the Gonâve Plate and microplates such as the Jamaica microplate. Major nearby tectonic features include the Puerto Rico Trench, the Cayman Trough, the Enriquillo-Plantain Garden fault zone, and the Septentrional-Oriente fault zone. Neighboring island nations and territories—Cuba, Hispaniola, Jamaica, Puerto Rico, Trinidad and Tobago—sit atop fault systems linked to the Motagua Fault, Swan Islands Transform Fault, and the Muertos Trough. Historical events such as the 1692 Port Royal earthquake, the 1780 Caribbean earthquake, and the 1867 Virgin Islands earthquake provide context for seismic hazard in the region. Institutions studying the setting include United States Geological Survey, Seismological Society of America, International Seismological Centre, University of the West Indies, Massachusetts Institute of Technology, Columbia University, and University of Puerto Rico.

Chronology of major events (2010–2019)

The decade opened with heightened attention after global events like the 2010 Haiti earthquake; subsequent notable events included sequences offshore of the Cayman Islands, the 2010s series in western Haiti, the 2014 Jamaica earthquake, the 2017 Puerto Rico earthquake sequence and the 2018 Hispaniola events. National and regional monitoring by agencies such as NOAA, Puerto Rico Seismic Network, Dominican Republic National Emergency Management, and CDEMA catalogued mainshocks and swarms. International collaborations—IRIS (seismology), GEOSCOPE, Observatoire Volcanologique et Sismologique d’Haïti—contributed waveform data identifying rupture mechanisms along transform faults and subduction-related thrusts. Sequences correlated with aftershock series recorded by Global Seismographic Network, Incorporated Research Institutions for Seismology, and datasets curated by EMSC and USGS National Earthquake Information Center.

Impacts and damage

Events in the sequence caused variable impacts across Port-au-Prince, Santo Domingo, Kingston, Jamaica, San Juan, Puerto Rico, Nassau, Bahamas, Montego Bay, and smaller communities including Jacmel and Les Cayes. Damage to infrastructure involved hospitals like Hospital General de la Plaza de la Salud, heritage sites such as Cathedral of Santo Domingo, ports in Bayonne and Port of Spain, and utilities serving Trinidad and Tobago Electricty Commission service areas. International relief actors—including Red Cross, Médecins Sans Frontières, United Nations Office for the Coordination of Humanitarian Affairs, Pan American Health Organization—responded to displacement, building collapse, and public health concerns. Economic centers like Kingston, San Juan, Santo Domingo experienced disruptions to tourism at destinations such as Punta Cana, Ocho Rios, Varadero, and St. Thomas, affecting airlines like Caribbean Airlines and American Airlines operations. Maritime and energy infrastructure incidents impacted ports like Port of Spain and oil facilities servicing companies such as BP and Chevron in regional operations.

Scientific studies and seismological analysis

Seismologists from California Institute of Technology, Massachusetts Institute of Technology, University of Cambridge, ETH Zurich, and Imperial College London applied methods including GPS geodesy, Interferometric Synthetic Aperture Radar from European Space Agency, focal mechanism inversion, and Coulomb stress modeling to analyze rupture processes. Paleoseismology studies referenced trenching results near the Enriquillo Fault and coral uplift records around Hispaniola and Jamaica to assess recurrence intervals. Peer-reviewed outlets—Science (journal), Nature, Geophysical Research Letters, Bulletin of the Seismological Society of America—published findings on stress transfer between the 2010 Haiti earthquake and subsequent events, viscoelastic relaxation, and induced seismicity hypotheses examined by groups at Princeton University and Rutgers University. International data repositories such as IRIS DMC and modeling consortia including Global Earthquake Model supported hazard re-evaluations by national agencies like USGS and British Geological Survey.

Emergency response and recovery

National responses involved ministries in Haiti, Dominican Republic, Jamaica, Puerto Rico, and Cuba, supported by regional coordination from CDEMA and international assistance from United Nations Development Programme, World Bank, Inter-American Development Bank, and humanitarian NGOs. Reconstruction programs referenced building codes influenced by standards from Pan American Health Organization and engineering studies from American Society of Civil Engineers. Military and coast guard assets—United States Southern Command, Royal Navy, Canadian Armed Forces—participated in search and rescue, while donor conferences convened by Organization of American States and bilateral partners such as United States Agency for International Development funded retrofitting projects. Communication and early warning improvements integrated systems from Caribbean Disaster Emergency Management Agency and tsunami warnings from Pacific Tsunami Warning Center adapted for Atlantic threats.

Socioeconomic and long-term effects

Long-term consequences included urban migration patterns in Port-au-Prince and Santo Domingo, changes in tourism demand in Punta Cana and Montego Bay, and shifts in insurance exposure managed by regional reinsurers and entities like CARICOM and Caribbean Catastrophe Risk Insurance Facility. Public health impacts intersected with organizations such as World Health Organization and Pan American Health Organization addressing mental health, sanitation, and vector-borne disease risks. Legislative and institutional reforms took place in disaster management offices influenced by models from FEMA and standards from International Organization for Standardization affecting planning in capitals including Havana and Bridgetown. Scientific capacity-building initiatives involved partnerships among University of the West Indies, Florida International University, New York University, and international research programs that enhanced preparedness across Caribbean nations.
