Malaysia Airlines Flight MH370 disappeared on 8 March 2014 with 239 persons on board. Despite three major underwater search campaigns covering approximately 232,000 km² of the southern Indian Ocean seafloor, the aircraft has not been located. This preprint presents a rigorous convergence analysis of four independent scientific methodologies: • Satellite communications analysis (BTO/BFO, UGIB 2020) • Terrain-aware sonar gap identification (Iannello Ulich 2023) • Controlled-ditching flight reconstruction (Blelly-Marchand 2023) All methods independently converge on a common impact corridor between 34.0°–36.0°S and 92.8°–94.0°E. The study identifies and precisely delineates a 30.5 km² unsearched terrain gap centred on 34.524°S, 93.840°E (the “Iannello Gap”), located on a steep bathymetric slope (~30% gradient). This area was not fully imaged due to terrain-induced sonar shadow zones during previous ATSB and Ocean Infinity operations. The Bayesian weighted centroid of the independent analyses is 34.25°S, 93.77°E (95% CI: ±0.45° latitude, ±0.38° longitude). As of February 2026, Ocean Infinity’s Phase 3 search has scanned 7,236 km² without confirmed discovery. The remaining area includes both the UGIB hotspot and the Iannello Gap. This convergence of independent physical evidence on a documented unsearched location provides strong scientific justification for prioritised completion of high-resolution AUV survey operations.
