The ancient Roman city of Complutum(Alcalá deHenares,Madrid), founded in the 1st century AD,was one of the most important cities ofHispania. The old Roman citywas destroyed, abruptly abandoned, relocated close by and rebuilt during the late 4th century AD. Destruction of the city and its relocation has not yet been explained by archaeologists. In this paper,with ourmultidisciplinary approach, we identify and characterize earthquake archaeological effects (EAEs) affecting the archaeological site, the La Magdalena, an agricultural holding 4 km from the core of Complutum. The most important EAEs in the site are liquefactions (sand dikes and explosive sand-gravel craters) affecting Roman structures, such as water tanks (cisterns), houses and graves. Ground liquefaction generated significant ground cracks, explosive craters and folds in foundations of buildings. Several other Roman sites throughout the valleywere also abandoned abruptly during the 4th century AD, in some caseswith EAEs of similar origin. This suggests the occurrence of a 5.0–6.6 Mw seismic event in the zone, in accordance with the minimum empirical limit of seismically-induced liquefaction and the maximum surface rupture length of the Henares fault.

la antigua ciudad romana de Complutum (Alcalá de Henares, Madrid) fue fundada en el s. I AD y fue una de las ciudades más importantes de Hispania. Complutum fue destruida, abandonada bruscamente, reubicada y reconstruida en una nueva localización en el s. IV AD. Las causas de la destrucción y la nueva localización de la ciudad son aún una incógnita para la arqueología. En este trabajo se muestran diferentes efectos arqueosismológicos de terremotos (EAEs) afectando al yacimiento de La Magdalena (una explotación agrícola situada a 4 km al NE del núcleo urbano de Complutum). El efecto geológico de origen sísmico que afectó al yacimiento es la licuefacción. Se pueden observar diques de arena y cráteres de gravas por explosión afectando a instalaciones romanas, como cisternas, casas o tumbas. Simultáneamente al abandono de La Magdalena también fueron abandonadas de forma brusca la ciudad de Complutum y varias villas romanas a lo largo del valle del Henares, en algunos casos con EAEs que pueden asociarse al mismo evento que destruyó el yacimiento de La Magdalena. Estos EAEs podrían estar generados por un terremoto de Mw = 5.0-6,6, utilizando los límites empíricos de licuefacción y ruptura cosísmica de la falla

Trying to decipher how palaeoseismic activity has influenced the altitudinal disposition of interglacial deposits is one of the main challenges that must be achieved in order to quantify relative sea-level changes between consecutive highstands. Likewise, identifying palaeoseismic features in an area with low instrumental seismic activity can implement the seismic record and contribute to better seismic hazard knowledge. In this sense, Cope basin (SE Spain) becomes a reference basin to undertake this kind of analysis, firstly because of excellent outcrop conditions and secondly because the sea-level record is undoubtedly conditioned here by both effects: climatically driven changes and local and regional seismotectonics.

The age of Neanderthal remains and associated sediments from El Sidrón cave has been obtained through different dating methods (14CAMS, U/TH, OSL, ESR and AAR) and samples (charcoal debris, bone, tooth dentine, stalagmitic flowstone, carbonate-rich sedim

Sea level and climate changes archived in various coastal environments during the last part of the last glacial and present interglacial periods are investigated by interpolating available geomorphology, sedimentology, palacontology and geochronology data. The coastal response to these changes depended on the environment and geographic location. Changes of sea level during the rising, transgressive phase are well recorded in the sedimentary filling of the estuaries, whereas during the phase of highstand they are best recorded in beach-barrier environments. The postglacial rise of sea level took place in two phases: a rapid rise until 6500 cal BP, and a second phase of near stability with minor oscillations of metric magnitude. Regarding climate changes, there is no record of changing temperatures in the coastal zones of southern Spain, although there is in precipitation and wind intensity/velocity. After 7-5cal ka BP, the general climatic trend towards aridity was punctuated by several short-lived (centennial) episodes of increased aridity that occurred with a millennial cycle, often coincident with Bond cool events and, in some cases, with decreases of sea surface temperatures. The absence of human intervention in vegetation composition until 2000 BP suggests that most environmental coastal shifts were climatically driven.
