A study suggests that a cosmic airburst, similar to the Tunguska event, destroyed the ancient city of Tall el-Hammam in the Jordan Valley around 1650 BCE. The airburst is believed to have caused widespread destruction, including the demolition of a 4-to-5-story palace complex and a massive mudbrick rampart. The event may have also led to a 300-600 year abandonment of the region due to hypersalinity. The study's findings are based on evidence of high-temperature materials and shocked quartz at the site.
