High-volume fluid injection can cumulatively increase underground pore pressure and induce earthquakes in regions unexpectedly far from injection wells, recent Kansas studies show.

Evidence for Gravity Tectonics After the Great Sumatra Quake
A new method that applies structural geology principles to aftershock analyses suggests that gravity-driven motion may occur during part of the seismic cycle.
How Earthquakes Start and Stop
Earthquakes: Nucleation, Triggering, Rupture, and Relationships to Aseismic Processes; Cargèse, Corsica, France, 2–6 October 2017
The Wicked Problem of Earthquake Hazard in Developing Countries
Earthquake preparation in Bangladesh is a conundrum, where crucial information is missing and investments often involve painful trade-offs.
Fiber-Optic Networks Can Be Used as Seismic Arrays
A new study repurposes telecommunications cables to harness sound from light. The method can accurately measure ground motion from distant earthquakes.
Drilling into a Future Earthquake
Researchers drill into a fault that is anticipated to rupture in coming decades to study fault structure and earthquake physics.
More Earthquakes May Be the Result of Fracking Than We Thought
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.
Damage Assessment by Laser Could Focus Postearthquake Response
Airborne lidar surveys taken before and after a powerful 2016 earthquake in Japan revealed the potential for such surveys to identify hard-hit buildings quickly.
Were Mexico’s September Quakes Chance or a Chain Reaction?
Last year, two major earthquakes—one 12 days after the first—shook Mexico. New analysis blames this very unlikely event on chance. But one of the pair may have triggered a third large nearby temblor.
Modeling Megathrust Zones
A recent paper in Review of Geophysics built a unifying model to predict the surface characteristics of large earthquakes.
