Oman
Oman is located in Asia and has a Low seismic risk classification. A total of 1 earthquakes have been recorded in the country's seismic history. The largest earthquake recorded in the country reached a magnitude of 4.4. With a population of 5,343,630 and a land area of 309,500 km², seismic events can have significant implications for infrastructure and public safety.
Seismic Overview
Oman's seismicity arises from two distinct tectonic environments. The dominant source is the Makran [[subduction-zone]] offshore in the Gulf of Oman and Arabian Sea, where the oceanic floor of the Gulf of Oman is being subducted beneath Iran and Pakistan along the Makran accretionary prism. This subduction zone is capable of generating great earthquakes and large-scale [[tsunami]]s — the 1945 Makran earthquake (magnitude 8.1) generated a tsunami that killed approximately 4,000 people in Pakistan and Oman and was felt as far as Mumbai. Oman's Hajar Mountains in the north represent an obducted ophiolite — a fragment of ancient oceanic crust from the Tethys Ocean that was thrust onto the Arabian continent during the Late Cretaceous. Active [[fault]] systems within the Hajar Mountains and at the Oman coastline contribute additional seismic hazard.
The most significant modern earthquake directly affecting Oman was the June 2007 Ghubbet Hasees event (magnitude 5.6) near Muscat, which caused panic and minor damage. The 1945 Makran earthquake generated [[tsunami]] waves that struck the Muscat coast, and historical accounts describe wave damage in Oman's coastal cities. The Masirah Island area off the eastern coast of Oman is positioned close to the Owen Fracture Zone, a major oceanic transform fault that occasionally generates moderate to large earthquakes. Events on the Owen Fracture Zone have been felt in Oman and Oman's offshore areas. The mountainous northern Oman region around Muscat and the Hajar range shows evidence of active faulting that warrants careful attention in urban planning.
The tectonic setting of Oman is dominated by its position on the passive margin of the Arabian Plate, but with the active Makran convergent margin less than 200 kilometres north of the Musandam Peninsula. The Musandam Peninsula itself forms a salient that projects northward into the Strait of Hormuz, and its complex folded and faulted geology reflects the local stress concentration at this corner of the Arabian Plate. The Owen Fracture Zone to the east of Oman represents the transform fault connecting the Carlsberg Ridge to the Makran subduction zone, completing the active plate boundary circuit around the Arabian Plate. GPS measurements in Oman show the slow but systematic northward motion of the Arabian Plate, confirming ongoing convergence with the Iranian margin. [[seismic-wave]] attenuation across the stable Arabian Platform is relatively low, meaning that energy from major Makran events reaches Muscat and other Omani cities with significant amplitude.

Frequently Asked Questions
Oman has a low level of seismic activity. Large earthquakes are infrequent but not impossible. A total of 1 earthquakes have been recorded in Oman's seismic history.
The largest recorded earthquake in Oman had a magnitude of 4.4. Earthquakes of this size can cause significant damage depending on depth, location, and local building standards.
Oman has had 1 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.
Oman is classified in the "Low" seismic zone, located in Asia. 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.
