[CEUS-earthquake-hazards] Recent earthquake research in the CEUS

*Recent publications that might be of interest to the CEUS audience:*



*Dense lower crust elevates long-term earthquake rates in the New Madrid
seismic zone
<http://onlinelibrary.wiley.com/doi/10.1002/2016GL070175/full>, *Authors:
Will Levandowski, Oliver S. Boyd, Leonardo Ramirez-Guzmán; Geophys. Res.
Letters; First published: 28 August 2016; DOI: 10.1002/2016GL070175

*KEY POINTS*

   1. Moment tensors show that principal stress directions at the New
   Madrid seismic zone are 30° different than surrounding regions
   2. Faults at New Madrid incompatible with regional stress but optimally
   aligned in local stress field
   3. Stress due to dense lower crust and tectonic stress interfere
   constructively, causing a regional deviatoric stress maximum at New Madrid
