New research suggests more earthquakes may be the result of fracking than previously believed

More Earthquakes May Be the Result of Fracking Than We Thought

by S. Witman 8 February 20188 December 2022

Scientists show small earthquakes caused by fracking near Guy-Greenbrier, Ark., in 2010 that could have been early indicators of high stress levels on larger faults deeper underground.

Researchers catalog more than 37,000 small earthquakes to see the bigger picture of seismicity along Italy’s Altotiberina fault.

The Curious Case of the Ultradeep 2015 Ogasawara Earthquake

by Terri Cook 28 December 20172 March 2022

Unusual ground motion associated with the deepest major earthquake in the seismological record is due to both its great depth and its origin away from the subducting slab.
