Earthquakes in Catania
Catania, Sicily's second-largest city, sits at the base of Mount Etna — Europe's largest and most active volcano — and above several active fault systems. The city was completely destroyed by the 1693 Val di Noto earthquake (M7.4) and rebuilt, only to be threatened by ongoing volcanic and tectonic seismicity.
Why Does Catania Face Earthquake Risk?
Catania faces seismic hazard from both tectonic faults and volcanic earthquakes from Mount Etna. The Malta Escarpment and other fault systems in the Sicilian Channel generate damaging earthquakes. The December 26, 2018 Etna earthquake (M4.9) caused significant damage to towns near the volcano.
Active Fault Systems
- Malta Escarpment
- Timpe Fault System (Etna)
- Iblean-Maltese Plateau Faults
Safety Advice
INGV maintains dense seismic monitoring around Etna. Catania's downtown Baroque historic center contains many unreinforced masonry buildings from the 18th century reconstruction. Check Sicily's detailed earthquake hazard maps for your specific location.
Historical Earthquake Context
The 1693 Val di Noto earthquake (M7.4) destroyed Catania and killed 60,000 people across eastern Sicily. The city was rebuilt in an elaborate Baroque style, which today makes it a UNESCO World Heritage Site. The 1818 and 1908 earthquakes also caused significant damage in Sicily.

FAQ
Frequently Asked Questions
Do Etna eruptions cause earthquakes in Catania?
Yes. Mount Etna generates thousands of earthquakes annually, ranging from imperceptible microseisms to damaging M5+ events. Most are volcano-tectonic earthquakes generated by magma movement and fault activation around the volcanic edifice.
How seismically active is Catania?
Catania and eastern Sicily sit in one of Italy's highest seismic hazard zones. The area experiences regular seismicity from both the Ibleo-Maltese escarpment fault system and from volcanic earthquakes associated with Etna. A M5+ earthquake occurs somewhere in eastern Sicily roughly every 1-2 years.
What was the largest earthquake in Catania's history?
The January 11, 1693 earthquake (estimated M7.4) is the largest in Sicilian recorded history and one of the deadliest in European history, killing approximately 60,000 people across eastern Sicily. It destroyed Catania entirely and prompted reconstruction of the city in the Sicilian Baroque style visible today.
Is Catania prepared for future earthquakes?
Catania has invested in seismic retrofitting of public buildings following EU and Italian government programs. However, the city's historic center contains many unreinforced masonry buildings that predate modern codes. INGV classifies the Catania area as Seismic Zone 1 — Italy's highest hazard classification.
Where can I see live earthquake data for Catania?
Track earthquakes near Catania on the Earthquake Globe app or at earthquakes.site/map?country=italy. INGV (terremoti.ingv.it) provides real-time Italian seismic data. The INGV Catania Section specifically monitors Etna seismicity and eastern Sicily at ct.ingv.it.
