Excavations and radiocarbon dating at Tall el-Hammam suggested most of its mud-brick walls vanished about 3,700 years ago. It’s thought that several Middle Ghor sites were inhabited for 2,500 years or more before the proposed impact.
Minerals that suddenly crystallized in blistering heat support the concept, archaeologist Phillip Silvia, of Christian institution Trinity Southwest University in Albuquerque, told the conference. Silvia and his colleagues have been excavating the city for more than a decade, Science News stated.
The enormous blast “not only [wiped] out 100% of the Middle Bronze Age cities and towns, but also [stripped] agricultural soils from once-fertile fields,” researchers wrote in an abstract. Shockwaves may have pushed super hot briney water from the Dead Sea over the east of the Middle Ghor, they added.
