Yes, Alicante sits in a genuine seismic zone. The province lies in the south-east of Spain, the country's most seismically active region, and Spain's National Geographic Institute (IGN) classifies much of Alicante province — especially the southern Vega Baja area — among the zones where seismic-resistant building codes must be applied. Risk here is best described as moderate to high by Spanish standards, though still far below countries like Turkey or Chile.

The underlying cause is the same slow collision that shapes seismicity across Murcia and Granada: the African plate pushes northward against the Eurasian plate, compressing the south-east of the peninsula and keeping numerous faults of the Betic mountain chain active. Several shallow faults run through Alicante province, capable of producing moderate-magnitude earthquakes. The Vega Baja del Segura, in the south near the border with Murcia, is the most exposed area, while the northern half of the province carries a somewhat lower — but not negligible — hazard.
History left a stark warning: the 1829 Torrevieja earthquake, estimated at around magnitude 6.6 with an epicentre in the Vega Baja, flattened several towns in the south of the province, killed hundreds of people, and forced entire villages to be rebuilt from scratch. No event of that scale has repeated since, but low-to-moderate seismic activity is a regular occurrence in the area. For residents, expats and anyone building along the Costa Blanca, following Spain's anti-seismic construction code remains the single most effective precaution.
Frequently asked questions
Is Alicante an earthquake zone?
Yes. Alicante province is one of the most seismically active in Spain, especially the southern Vega Baja del Segura, which Spain's building code (NCSE) classifies among the country's higher-hazard zones.
How often does Alicante get earthquakes?
Small tremors are common; the wider Alicante area records roughly 170 quakes a year on average, though the vast majority are too weak (below magnitude 2) to be felt.
What was the biggest earthquake near Alicante?
The 1829 Torrevieja earthquake, around magnitude 6.6, is the strongest on record in the province. It devastated several towns in the Vega Baja and remains Spain's deadliest seismic event of the 19th century.
Has Alicante had a magnitude 7 earthquake?
Not in the modern instrumental record for the city itself, but a magnitude 7.3 event was recorded offshore near the Alicante coast on 10 October 1980, the strongest detected near the province since 1900.
Why is Alicante seismically active?
The African plate pushes north against the Eurasian plate, compressing south-east Spain and keeping shallow faults of the Betic mountain chain — such as the Bajo Segura and Crevillente faults — active.
Which part of Alicante province is most at risk?
The Vega Baja del Segura in the south, near the border with Murcia, carries the highest hazard. The northern half of the province has comparatively lower, though not negligible, risk.
Are buildings in Alicante earthquake-resistant?
Since 1994 all new construction in classified zones must follow Spain's anti-seismic code (NCSE-02), which sets stricter design requirements for foundations and structures in high-hazard municipalities.
Is it safe to live in Alicante given the earthquake risk?
Yes for the vast majority of residents. Risk is moderate by Spanish standards and far below countries like Turkey, Greece or Chile; following local building codes is the main precaution needed.
