PUBLIC LECTURE: Carbonate Deposits in Roman Aqueducts
|Carbonate Deposits in Roman Aqueducts : a Data Source for Archaeology, Palaeoclimate and Archaeoseismology
A public lecture by Cees Passchier, Johannes Gutenberg University, Germany.
Carbonate deposits in aqueducts are a new high-resolution data source for palaeoclimate, spring hydrology and earthquake occurrence.
Ancient aqueducts are also a promising archive for archaeoseismic studies. An aqueduct channel that served the Roman city of Ephesos in western Turkey was dislocated by an earthquake that probably occurred in 178 CE, after the original channel had functioned for less than 35 years.
The fault responsible for the displacement may still constitute a seismic and tsunami hazard for the Turkish west coast. These observations imply that lamination in carbonate deposits in Roman aqueducts can be used for relative dating of aqueduct construction and maintenance and to obtain data on external factors that influenced the aqueducts, such as palaeoclimate and natural hazards. As many aqueducts of nearly identical channel geometry are present in different climate zones and with different source water characteristics, these data hold high promises as seasonally resolved archives of hydrology and climate, and of earthquakes.
