In contrast to the IAA report on the Givat Yona excavations (previously criticized here), Ran Shapira has written a well-researched and accurate report on the excavations of the site within modern Ashdod.
A commenter on the previous blog post also observed that the place “of Saint Jonah” is depicted on the Medeba Map (c. AD 600). As can be seen in the photo below, its location is quite a bit north of Ashdod and in the area of Dan’s (original) tribal allotment. The map probably refers to Tell Yunis, 4 miles (6.5 km) south of Joppa.
It may also be noted that the Survey of Western Palestine records about half a dozen sites preserving the name Jonah, most of them in Galilee.
