Resumen
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.
The ancient Roman city of Complutum (Alcalá de Henares, Madrid) was founded in the first century AD and it was one of the most important cities of Hispania. Complutum was destroyed, abruptly abandoned, relocated in a new location and rebuilt in the fourth century AD. The destruction of the city and its new location is still a mystery to the archaeologists. In this paper we show different earthquake archaeological effects (EAEs) affecting the La Magdalena site (an agricultural holding located 4 km away from the core of Complutum). The most important earthquake geological effect affecting the site is the occurrence of liquefaction processes (sand dikes and gravel blow craters) affecting roman facilities, such as water tanks, houses or tombs. Several archaeological sites of Roman origin were abruptly abandoned along the Henares valley simultaneously with La Magdalena site and Complutum, in some cases with EAEs with similar origin to those recorded at la Magdalena site that could be associated with the same event that destroyed this site. These EAEs could be associated to an earthquake of Mw=5.0-6.6, using the empirical limit of liquefaction and fault coseismic rupture.
