In late January 2026, the town of Niscemi in the province of Caltanissetta, Sicily (Italy) has been struck by a massive landslide triggered by intense and prolonged rainfall associated with Storm Harry. This geological disaster has rapidly evolved into one of the most serious emergencies in recent Sicilian memory — with widespread evacuations, infrastructure collapse and ongoing risk to residents and buildings.
📍 Where Is Niscemi?
Niscemi is a historic town of about 25,000–30,000 residents in central-southern Sicily, roughly 22 km from Gela and 100 km from Catania. It sits on a plateau of clay and sandy soils, which are vulnerable to erosion and water saturation — factors that have made the landscape prone to instability.
🌧️ What Triggered the Landslide?
The landslide began after days of relentless rainfall brought by Storm Harry, a powerful weather system that dumped exceptional amounts of water across Sicily and other southern Italian regions.
The saturated ground weakened the soil’s natural cohesion, causing the land to break away along a front stretching at least 4 kilometers (2.5 miles). In some areas, vertical fissures and canyon-like drops up to 50 meters deep have formed.
🔴 Scope of the Impact
Evacuations
- Between ~1,000 and 1,500 residents have been evacuated from neighborhoods including Sante Croci, Trappeto, and Via Popolo.
- Many families have moved in with relatives, others are housed in emergency centers such as a local sports hall.
- Authorities widened the safety zone up to 150 meters from the active landslide front due to ongoing ground movement, increasing displacement numbers.
Infrastructure Damage
- Primary access roads such as Provincial routes SP10 and SP12 have been closed as unstable ground makes them unsafe.
- Some parts of the town are nearly isolated due to damaged or blocked routes.
- Several houses near the landslide are now deemed uninhabitable or at imminent risk of collapse.
Ongoing Movement
- Geological monitoring confirms the landslide is still active and may continue moving, meaning further evacuations or damage remain possible.
🏛️ Government & Emergency Response
State of Emergency
The Italian government has declared a state of emergency for Sicily, Sardinia, and Calabria due to the widespread damage caused by Storm Harry, which includes the landslide at Niscemi. This declaration unlocks emergency funds and rapid response measures.
Civil Protection Efforts
- National and regional civil protection teams, led by Fabio Ciciliano, are coordinating evacuations, structural assessments, and stabilization efforts.
- Local authorities, including Mayor Massimiliano Conti, are working to manage the situation and maintain public safety.
Economic and Social Concerns
Local business groups and civic organizations are urging broader government support, underlining potential long-term economic impacts if the town remains cut off or heavily damaged.
🏠 Human Stories From Niscemi
Residents have shared experiences of waking up to cracks in the earth, collapsing roads, and the sudden need to leave their homes. While no fatalities have been reported so far, the psychological and material toll on the community is profound.
📊 Why This Landslide Matters
This isn’t just a local event — it’s part of a larger pattern of extreme weather extremes in the Mediterranean region, which scientists link to climate change. Storm Harry’s impact has been severe, not only in Sicily but also in other parts of southern Italy, with floods and landslides recorded in multiple areas.
Environmental historians and geologists note that landslides in Niscemi were possible due to a combination of natural geology and long-standing maintenance and planning issues. While heavy rain was the immediate trigger, underlying risk factors predated the storm.
🧠 What’s Next for Niscemi?
Short-Term Priorities
- Continued monitoring and stabilization of the active landslide front.
- Ensuring safe housing and care for displaced residents.
- Restoration of roads and essential services where possible.
Long-Term Challenges
- Geological surveys and hazard mitigation planning to reduce future risk.
- Permanent relocation for families whose homes can never be safely reoccupied.
- Investing in infrastructure strengthening and erosion control.
