The cities of Pompeii, Herculaneum and Stabiae were also originally supplied by the aqueduct but being destroyed and covered by the eruption of Mount Vesuvius in 79 AD they did not appear on this list. The next major eruption in 472 AD left the aqueduct covered in ash and 3.5 km of the duct collapsed because of this. This cut off the supply of water to all the towns except Nola and Acerrae. The poor administrative and economic situation in Campania at this time, and Italy in general, prevented major repairs to the Augusta. Written references to aqueducts in Naples after this time only refer to other aqueducts that were now in the area.
