Illinois Basin carbon storage site's microseismicity linked to CO2 injection causing microearthquakes.
Microseismicity at an Illinois Basin carbon storage site is likely caused by pore pressure diffusion from CO2 injection, according to a study in the Bulletin of the Seismological Society of America. The pressure diffusion may have destabilized existing faults, causing microearthquakes ranging from Mw -2 to 1. This study is significant due to similarities between CO2 and wastewater injection from oil and gas operations, which have induced small to moderate-sized earthquakes globally.
