説明
<jats:title>A silent and periodic earthquake trigger</jats:title> <jats:p> Large earthquakes that hit places such as Japan seem to be preceded by subtle and silent deformation. Uchida <jats:italic>et al.</jats:italic> show that these “slow-slip events” are quasi-periodic in the megathrust zone in Japan. Slow-slip events occurred every 1 to 6 years and frequently were correlated with large earthquakes, including the great 2011 Tohoku-oki earthquake. The quasi-periodic behavior stretches back to at least 1930 and provides an important constraint for seismic hazard assessment in the region. </jats:p> <jats:p> <jats:italic>Science</jats:italic> , this issue p. <jats:related-article xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="doi" issue="6272" page="488" related-article-type="in-this-issue" vol="351" xlink:href="10.1126/science.aad3108">488</jats:related-article> </jats:p>
