Three non-destructive tests find two voids behind Menkaure's east face. Pyramid of Djoser scanned using electrical resistivity tomography, ground penetrating radar, and ultrasonic testing Data merged using image fusion technique for more reliable void detection Anomaly A1 is 1 by 1.5 meters, begins 1.4 meters deep
Scientists combined electrical resistivity tomography, ground penetrating radar, and ultrasonic testing to scan Menkaure's pyramid. Found two anomalies (A1: 1×1.5m, A2: 0.7×0.9m) interpreted as air gaps. Results published as conference paper at NDTCE 2025 (NDT.net).
Key Facts
- Pyramid of Djoser scanned using electrical resistivity tomography, ground penetrating radar, and ultrasonic testing
- Data merged using image fusion technique for more reliable void detection
- Anomaly A1 is 1 by 1.5 meters, begins 1.4 meters deep
- Anomaly A2 is 0.7 by 0.9 meters, begins 1.13 meters deep
- Both anomalies interpreted as air gaps from combined scan data
- Maximum scan depth achieved was 3.5 meters - does not mean voids extend that deep
- Paper published in journal NDT and E International
- Scientists Hani Halal previously accurately predicted Great Pyramid's northface corridor using non-destructive tests
