ERT survey reveals hidden row of caves below Treasury tombs. ERT (electrical resistivity tomography) survey conducted inside excavated tombs 62D and E found another row of caves below The newly discovered caves have identical geophysical signatures to the five Treasury side tombs Red color on ERT indicates high resistivity: voids, cavities or caves
Ground-penetrating radar surveys at Petra's Treasury found geophysical signatures consistent with hidden chambers below. High resistivity signatures indicate voids or cavities. Deeper structures remain unexplored—the survey only tested shallow underground, with potential for more discoveries.
Key Facts
- ERT (electrical resistivity tomography) survey conducted inside excavated tombs 62D and E found another row of caves below
- The newly discovered caves have identical geophysical signatures to the five Treasury side tombs
- Red color on ERT indicates high resistivity: voids, cavities or caves
- The deeper underground caves protrude further out from the treacherous rock cliff
- ERT only tested about 6 meters (20 ft) underground, suggesting more structures may exist deeper
- The north region shows major cave configuration comparable to the size of the Treasury's chambers
