Researchers studying the Gofar oceanic transform fault off Ecuador found that barrier zones—networks of tiny, water-filled faults—act as active brakes, using dilatancy strengthening to buffer rock and prevent runaway earthquakes. Data from two long-term ocean-bottom seismic deployments show similar behavior across fault segments, suggesting these features may regulate quake size on other oceanic faults and could improve seismic models.
New research has revealed that oceanic transform faults serve as significant CO2 sinks, challenging previous understanding of the Earth's geological carbon cycle. These findings emphasize the crucial role of natural geological emissions in shaping Earth's climate history and highlight the need for a deeper understanding of these processes in the context of addressing contemporary climate change. The study, published in the Proceedings of the National Academy of Sciences, sheds light on the previously underestimated role of transform faults in carbon cycling and provides insights into long-timescale carbon fluxes between Earth's mantle and the ocean/atmosphere system.
