Front: The Array Network Facility (ANF), funded by the National Science Foundation Earthscope-USArray project, launched in April 2004 with real-time acquisition of continuous three-component broadband seismic data from just 62 regional stations in California. Astiz et al. (this issue) chronicle the past 10 years of development, during which ANF expanded to cover the United States from coast to coast. The center map on the cover shows ANF-located epicenters from the past decade; the smaller maps, counterclockwise from upper left, show the growth in the number of ANF’s stations nationwide. Back: A rare local-magnitude 4.4 earthquake that struck near Paradox, Colorado, on 24 January 2013 was strongly felt by nearby residents. Block et al. (this issue) investigated and concluded that the event was induced by long-term fluid injection at the Paradox Valley Unit, a salinity control facility operated by the U.S. Bureau of Reclamation. The 24
January 2013 event is one of a cluster of such injection-related seismic events in the area to date, the authors report; it is also the largest such seismic event and the one with an epicenter located the farthest from the injection site.
