Response to “Comment to Shreve and Delgado (2023)—‘Trapdoor Fault Activation: A Step Toward Caldera Collapse at Sierra Negra, Galapagos, Ecuador’ by LaFemina et al. (2025)”

LaFemina et al. (2025, https://doi.org/10.1029/2024JB030621 ) argue that the 2018 Sierra Negra eruption represents caldera resurgence based on uplift at the southern trapdoor fault in the caldera. We clarify that our original study (Shreve & Delgado, 2023, https://doi.org/10.1029/2023jb026437 ) focused exclusively on the co‐eruptive phase, not the entire decade‐long unrest sequence. We show that the eruption produced net caldera subsidence along the floor, not uplift, and that the observed co‐eruptive normal faulting is inconsistent with the definition of caldera resurgence as understood for felsic calderas. In contrast, the geophysical signals recorded during the eruption resemble those recorded during basaltic caldera collapses.
