Fig. 7: Main intrusive structure and mechanism of eastern flank displacement.
From: 22 years of satellite imagery reveal a major destabilization structure at Piton de la Fournaise
a Map view of the identified rift zones (RZ). Flank slip associated with sheared intrusions took place in January 2004, March–May 2007, October 2019, and September 2020. b Cross-section showing the main intrusive destabilization structure, color-coded to reflect the amount of slip. Main geological features from Fig. 3 are indicated for reference. Earthquake locations31,39,40,77 are marked using the same legend as in Fig. 3. The spoon-shaped geometry is from the polynomial regression shown in Fig 5. c Mean opening and slip from all inverted models computed with a moving mean of 200 m radius.
