Valencia region in eastern Spain experienced catastrophic flooding caused by an isolated high-altitude, low-pressure system, known locally as a DANA
In 2024, the Valencia region in eastern Spain experienced catastrophic flooding caused by an isolated high-altitude, low-pressure system, known locally as a DANA (Depresión Aislada en Niveles Altos). This system brought unprecedented rainfall, with some areas recording up to 500 mm (about 20 inches) of rain in just hours in the month of October. Such intense precipitation led to severe flash floods that inundated streets, damaged infrastructure, and swept away vehicles. The affected areas included both urban centers like Valencia and nearby towns such as Utiel and Paiporta.The flooding led to at least 62 deaths, with some people still missing. The Spanish military and emergency units deployed over 1,000 personnel, using helicopters and other means to rescue people trapped by rising waters. Extensive damage occurred to roads, railways, and other infrastructure, and services like rail and flights in Valencia were disrupted. High-speed rail service between Valencia and other major cities was halted, and local schools and businesses remained closed for safety.Satellite imagery from NASA and the European Space Agency highlighted how floodwaters transformed the landscape, covering agricultural lands and filling rivers and wetlands with sediment. The rapid response, including real-time satellite mapping, assisted in emergency efforts, showcasing the scale of damage and areas in urgent need of recovery support.
