Through Americas

This site is notable for the exceptional preservation of a Classic period settlement, which was rapidly buried by ash from an eruption of the Loma Caldera around AD 600. The abundance of paleoethnobotanical remains has provided important insights into the daily life of ancient Maya agricultural communities. Among the most significant discoveries is a manioc field, the earliest known evidence of manioc cultivation at an archeological site in the New World. The site is thought to have been occupied between AD 200 and AD 600. Joya de Cerén was inscribed on the UNESCO World Heritage List in 1993 in recognition of its archeological significance and is a major tourist attraction in El Salvador.

Abandonment of Joya de Cerén

The population of the village, around the time of its abandonment 1400 years ago, has been estimated to be 200 people. The eruption of the Loma Caldera volcano caused 10 meters of pyroclastic debris to settle over the site. The site was remarkably well preserved due to the low temperature of ash and very fast ashfall, a 4 - 8 meter thick layer having blanketed the town in the space of a few hours. The use of plaster casting by archaeologists similar to the one used in Pompeii assisted in their identification of fruiting plants, abundance of beans in storage, and mature maize to predict the eruption happened in August or September.

Guava, agave, cacao, and manioc were some of the major crops to the community. Based on crack patterns observed from the relatively earthquake-resistant wattle-and-daub walls and adobe columns at Joya de Cerén, scholars suggest that an earthquake measuring 4.0 on the Richter scale preceded the eruption, giving residents time to flee the site. Further, possible steamy emissions from the volcano may have alerted residents of the impending danger, but only inferences can be made about what exactly warned them. It is unclear to scholars if the duration of the eruptions lasted a few days or a few weeks. The position of artifacts at the site have led scholars to suggest that the evacuation of Joya de Cerén happened in the early evening: shovels and other agricultural work equipment were found stored near the domestic structures, and fires had been lit in hearths. Also, sleeping mats had not yet been rolled out on the domicile floor. No human remains have been discovered at the ancient Maya site.
