Mauritania
Mauritania is located in Africa and has a Low seismic risk classification. A total of 0 earthquakes have been recorded in the country's seismic history. With a population of 4,927,532 and a land area of 1,030,700 km², seismic events can have significant implications for infrastructure and public safety.
Seismic Overview
Mauritania spans a vast area of the western Sahara and the Atlantic coastal zone of West Africa. The country sits on the western edge of the West African craton and the Reguibat Shield — a large exposure of ancient Archean and Proterozoic basement rocks that represents one of the nuclei of the ancient African continent. This stable geological setting produces very little natural seismicity, and Mauritania is among the least seismically active countries in Africa.
The Mauritanide orogenic belt runs along the country's western edge — an ancient mountain-building zone that was active during the Paleozoic assembly of Gondwana. These ancient thrust structures have been inactive for hundreds of millions of years and are mechanically welded to the craton. The Atlantic passive margin off Mauritania's coast formed during the Mesozoic opening of the Central Atlantic and is likewise geologically quiet.
Occasional low-magnitude earthquakes have been detected in the Mauritania-Senegal offshore zone along ancient buried transform faults, but these events are of no practical consequence onshore. The Atlas Mountains in Morocco to the northeast generate occasional earthquakes, but by the time [[seismic-wave]] energy reaches Mauritania it has attenuated to imperceptible levels.
Historical earthquake records for Mauritania are blank — no damaging event has ever been documented in the country's recorded history. [[magnitude]] events above 4.0 are not reliably catalogued within Mauritania's borders. Building design and disaster risk planning in Mauritania focus entirely on non-seismic hazards: drought, desertification, locust outbreaks, and coastal flooding. Mauritania represents one of the world's lowest seismic-hazard environments.

Frequently Asked Questions
Mauritania has a low level of seismic activity. Large earthquakes are infrequent but not impossible. A total of 0 earthquakes have been recorded in Mauritania's seismic history.
Mauritania has had 0 recorded earthquakes. This count includes events of all magnitudes detected by seismic monitoring networks. The actual number of earthquakes may be higher, as smaller events can go undetected.
Mauritania is classified in the "Low" seismic zone, located in Africa. Seismic zones indicate the relative level of earthquake hazard based on historical activity, geological conditions, and proximity to tectonic plate boundaries.
During an earthquake, Drop, Cover, and Hold On. Get under a sturdy desk or table, protect your head and neck, and hold on until shaking stops. Move away from windows and heavy objects. After the earthquake, check for injuries and be prepared for aftershocks.
Country earthquake risk is assessed using several factors: proximity to tectonic plate boundaries, historical seismicity (frequency and magnitude of past events), geological conditions, population density in seismic zones, and building code enforcement. QuakeFYI assigns seismic zones from 0 (no risk) to 4 (very high) based on these factors.
A seismic zone is a geographic area classified by the level of earthquake hazard. Zone 0 has negligible risk, Zone 1 has low risk, Zone 2 has moderate risk, Zone 3 has high risk, and Zone 4 has very high risk. These zones are determined by historical earthquake data, tectonic setting, and geological conditions.
Countries along the Pacific Ring of Fire experience the most earthquakes. Japan, Indonesia, Chile, the Philippines, and Iran consistently record the highest seismic activity. The United States (especially Alaska and California), Turkey, and Mexico are also among the most seismically active nations.
Population density amplifies earthquake risk because more people and infrastructure are exposed to potential damage. A magnitude 7.0 earthquake in a densely populated city can cause thousands of casualties, while the same event in an uninhabited area may cause none. Building codes and emergency preparedness greatly reduce risk in populated areas.
Seismic density measures the concentration of earthquake activity relative to a country's land area, expressed as earthquakes per 1,000 square kilometers. A high seismic density indicates frequent earthquake activity per unit area, helping compare seismic risk between countries of different sizes.
