Les pluges extremes com la DANA a València podrien repetir-se cada 47 anys, segons un estudi del Centre de Política de Sòl i Valoracions de la UPC - UPC Universitat Politècnica de Catalunya

Les precipitacions extremes registrades durant la DANA a València podrien tenir un període de retorn de només 47 anys, i no de 500 com s’havia estimat inicialment.

➡️ Així ho indica un estudi del Centre de Política de Sòl i Valoracions (CPSV) de la #UPC.

A map showing the distribution of fatal landslides in 2024. There are two clusters in South Asia, plus others in SE Asia, East Asia, East Africa, SE Brazil, the northwest of South America and in Central America. Author's own data, published under a CC license. If you want a higher resolution version, please contact the author.

The cumulative total number of fatal landslides in 2024 compared with previous years. The graph shows that 2024 was exceptional in every respect, with the December total exceeding every previous years by a huge margin.

I have now posted my provisional analysis of fatal landslides in 2024 on my blog. In total, 708 fatal landslides (excluding those triggered by an earthquake), cost 4,492 lives. This is far higher than in any previous year for which I have data.
