Fig. 6: Summary schematic of the intraslab rupture and mechanism transition for the Mw 7.4 event.
From: Deep intra-slab rupture and mechanism transition of the 2024 Mw 7.4 Calama earthquake
The earthquake ruptured seismic asperities of various scales (red polygons), and penetrated through the 650 °C boundary allowable for serpentine dehydration, which suggests transitioning to another mechanism, likely shear thermal runaway. Gray dots represent seismicity that delineates the upper and lower seismic zones.
