説明
<jats:title>Slow Stick-Slip</jats:title> <jats:p> While the character of slow earthquakes has been approximated for some time, precise slip histories and the underlying mechanisms have remained elusive. <jats:bold>Kaproth and Marone</jats:bold> (p. <jats:related-article xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="doi" issue="6151" page="1229" related-article-type="in-this-issue" vol="341" xlink:href="10.1126/science.1239577">1229</jats:related-article> ; published online 15 August) have made laboratory observations of repetitive, slow stick-slip in fault-zone materials and developed a mechanical explanation for how earthquake-like dynamic slip nucleation could start and then arrest so as to produce slow slip. As preseismic slip is a precursor to rupture, temporal variations in elastic wave speeds should be monitored in regions of high seismic hazard. </jats:p>
