説明
<jats:title>Gravity gets into the earthquake game</jats:title> <jats:p> Earthquakes generate large movements of mass, which slightly change the gravitational field. Unlike the elastic waves that propagate from the earthquake, the gravity perturbations travel at the speed of light. Vallée <jats:italic>et al.</jats:italic> have finally observed these gravity perturbations in seismometer records from the great Tohoku earthquake in Japan in 2011. The signal would have allowed an accurate magnitude estimation in minutes, rather than hours, for this catastrophic earthquake. </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="6367" page="1164" related-article-type="in-this-issue" vol="358" xlink:href="10.1126/science.aao0746">1164</jats:related-article> </jats:p>
