The vertical fingerprint of earthquake cycle loading in southern California

Howell et al find a coherent pattern of uplift and subsidence straddling the San Andreas fault system in southern California using vertical velocities derived from global positioning system data, improving the quantification of seismic hazards in southern California and beyond.

Sam Howell's research of San Andreas fault system earned a spot in the 2016 Popular Mechanics Breakthrough Awards!

Injection induced seismicty

Very interesting collection of papers in The Leading Edge regarding injection-induced seismicity.  Fluid injection during petroleum production can cause crustal movement with significant seismic energy. 

"Preliminary hazard models indicate that areas experiencing the highest rate of earthquakes in 2014 have a short-term (one-year) hazard comparable to or higher than the hazard in the source region of tectonic earthquakes in the New Madrid and Charleston seismic zones."
