Geologic carbon storage is unlikely to trigger large earthquakes and reactivate faults through which CO ₂ could leak

Significance Geologic carbon storage remains a safe option to mitigate anthropogenic climate change. Properly sited and managed storage sites are unlikely to induce felt seismicity because ( i ) sedimentary formations, which are softer than the crystalline basement, are rarely critically stressed; ( ii ) the least stable situation occurs at the beginning of injection, which makes it easy to control; ( iii ) CO 2 will dissolve into brine at a...
