Portugal experiences significant earthquakes, especially along the southern coast and the Azores-Gibraltar fault zone. The 1755 Great Lisbon earthquake (estimated M8.5–9.0) destroyed Lisbon and generated a massive tsunami, killing up to 100,000 people. Major faults include the Azores-Gibraltar Fracture Zone, the Lower Tagus Valley fault, and the Alentejo thrust. Notable quakes include 1755 Lisbon (M8.7), 1969 Horseshoe (M7.8), 1969 Algarve (M7.0). The seismic risk is moderate to high. Tectonically, Portugal lies near the boundary between the African and Eurasian plates, with active thrusting and strike-slip faulting. This page provides real‑time USGS data and historical context for Portugal.

The region is defined by Azores-Gibraltar Fracture Zone, Lower Tagus Valley fault, Alentejo thrust, and the risk level is classified as Moderate to High. With a population of 10.3 million, understanding local seismic hazards is crucial.
Portugal lies on Convergent boundary – African Plate colliding with Eurasian Plate. The movement of these plates builds up stress, which is released as earthquakes. In subduction zones, one plate dives beneath another, generating some of the largest quakes on Earth. In some regions, strike‑slip faults produce frequent moderate earthquakes.

The strongest recorded earthquake in Portugal was the 1969 Algarve earthquake (M7.0). 1969 Algarve (M7.0)
Portugal experiences low to moderate seismic activity, with occasional felt earthquakes, according to USGS historical data.
The most recent major earthquake in Portugal was the 1969 Algarve earthquake (M7.0). 1969 Algarve (M7.0)
Yes. Portugal is crossed by Azores-Gibraltar Fracture Zone, Lower Tagus Valley fault, Alentejo thrust, making it prone to seismic activity. The seismic risk level is classified as Moderate to High.
Drop, cover, and hold on. Stay away from windows, and if outdoors, move to an open area. After the shaking stops, check for injuries and be ready for aftershocks. Prepare an emergency kit with water, food, first aid, and a flashlight.
