This month's offering of “Bright Spots” consists of one technical paper and two case histories. These topics span from crustal reflectivity mapping using teleseismic body waves to a 3D magnetic survey of porphyry copper in Alaska and further afield to studies of seismic moment tensor solutions from microearthquakes from hydrofracturing in shale—global geophysics and exploration geophysics working together to expand our understanding of the subsurface.
