<p><span>The ongoing, dramatic increase in seismicity in the central United States that began in 2009 is believed to be the result of injectionâinduced seismicity (</span><span class="xref-bibr">Ellsworth, 2013</span><span>). Although the basic mechanism for activation of slip on a fault by subsurface fluid injection is well established (</span><span class="xref-bibr">Healy <i>et al.</i>, 1968</span><span>; </span><span class="xref-bibr">Raleigh<i>et al.</i>, 1976</span><span>; </span><span class="xref-bibr">Nicholson and Wesson, 1992</span><span>; </span><span class="xref-bibr">McGarr <i>et al.</i>, 2002</span><span>; </span><span class="xref-bibr">Ellsworth, 2013</span><span>), the occurrence of damaging </span><i>M</i><span>≥5 earthquakes and the dramatic increase in seismicity in the central United States has brought heightened attention to this issue. The elevated seismicity is confined to a limited number of areas, and accumulating evidence indicates that the seismicity in these locations is directly linked to nearby industrial operations. This </span><i>Seismological Research Letters</i><span> (</span><i>SRL</i><span>) focus section presents a selected set of seven technical papers that cover various aspects of this topic, including basic seismological and groundâmotion observations, case studies, numerical simulation of fault activation, and risk mitigation.</span></p>
