Abstract
El 29 de octubre de 2024, en el marco de una situación climática de DANA, una riada afectó gravemente a parte del casco histórico de la localidad albaceteña de Letur. Aparte de los efectos directos, que implicaron seis muertes y cuantiosos daños, se observaron grietas y desplazamientos de hasta medio metro en edificios y pavimentos de algunos sectores. El pueblo se emplaza en un promontorio travertínico con escarpes de decenas de metros, que avanza sobre el borde de una cuenca miocena, colmatada en el Plioceno. Se encuentran evidencias cartográficas de que el edificio tobáceo es altamente inestable y está sujeto a una rápida evolución geomorfológica, que es apreciable mediante técnicas InSAR. El presente trabajo constituye un estudio preliminar de los factores que condicionan la evolución del promontorio y de las interacciones entre las inundaciones, la actividad antrópica y la estabilidad geotécnica, que implican importantes riesgos.

On October 29, 2024, in the context of a DANA climate situation, a flood seriously affected part of the Letur’s old town (Albacete, south Spain). Apart from the direct effects that involved six deaths and extensive damage, cracks and displacements of up to half a meter were observed in buildings and pavements in some sectors. The town is located on a travertine promontory with scarps of tens of meters, which advances on the edge of a Miocene basin filled in the Pliocene. There is cartographic evidence that the tuffaceous building is highly unstable and is subject to rapid geomorphological evolution, which is appreciable through InSAR techniques. This work constitutes a preliminary study of the factors that condition the evolution of the promontory and the interactions between floods, anthropic activity and geotechnical stability, which imply significant risks.
