CO2 injection has already caused more than 29,000 earthquakes

The Human-Induced Earthquake Database is an academic project to track levels of induced seismicity. This chart shows some of their data recording earthquakes specifically resulting from CO2 injections.

Most of these are very small: not a single seismic event from CO2 storage in Weyburn has had a positive magnitude, for instance, meaning none of the earthquakes they caused could be felt by humans. Seismic events from injections at the Texan Cogdell Field, however, have reached a magnitude of 4.4.
