Okay, this is especially interesting. Rockslides from cliffs above the Jordan River have dammed the water many times in recorded history, most recently in 1956. The entire river valley sits on a fault line, a crack in the earth’s shifting crust. In 1927, a devastating earthquake produced a landslide that blocked the river for 21 hours—incredibly, at what some scholars say is the same site Joshua reported: “Adam” (3:16). The location today is known by the similar-sounding name of Damiya. It’s about 20 miles (32 km) upstream from the fords near Jericho. The epicenter of that quake was somewhere near where the Israelites camped before crossing the river. Some scholars put the epicenter north of the camp, near the Damya Bridge some 15 miles (24 km) north of the southern fords of the river. Others place it beneath the Dead Sea, about 20 miles (30 km) south of the river fords. Split the difference and the epicenter would have been below where the feet of the Israelite priests reportedly stood more than 3,000 years ago, when the river stopped flowing for them.
