We built a dataset of natural hazard events (earthquakes, floods, landslides, rockfalls, ground subsidence, and wildfires) in the Garrotxa region (Spain) covering 1900–2023. It includes 1,049 events retrieved from official records, newspaper articles, scientific studies, and oral testimonies. The data show links between some hazards and provide more local detail than existing databases, helping improve risk understanding and planning, and providing a framework for multi-hazard risk analysis.
