Incoming links: Seismic evidence for the fault origin of oceanic deeps by Hugo Benioff
Hugo Benioff Created 2026-10-25 Updated 2026-11-05
Hugo Benioff investigated whether sequences of earthquakes could reveal large faults extending far below the Earth's surface. His 1949 study used accumulated estimates of elastic-rebound strain increments to compare events as possible movements on one structure. He interpreted the Tonga–Kermadec and South American sequences as activity on great inclined faults reaching roughly depth. The observations helped establish the deep geometry later associated with a Wadati-Benioff zone; the original fault interpretation belongs to the historical development preceding modern subduction theory.[ref]
