Abstract

Tectonic stresses are transmitted to a fault through the surrounding fractured and altered rock, or fault zone. Measuring how seismic velocities (wavespeeds) behave in a fault zone offers a rare insight into the properties and deformation mechanisms operating within it. However, most wavespeed monitoring methods only resolve velocity changes at very shallow depths (<5 km below the surface). This constraint has obscured the deeper parts of fault zones where earthquakes initiate and grow. On page 1256 of this issue, Bryan et al. (1) report the evolution of seismic velocities from 0 to 20 km below Earth’s surface around a fault zone by using teleseismic receiver functions. This approach could help scientists understand the processes that operate deep within a fault zone.

期刊介绍： Science is a leading outlet for scientific news, commentary, and cutting-edge research. Through its print and online incarnations, Science reaches an estimated worldwide readership of more than one million. Science’s authorship is global too, and its articles consistently rank among the world's most cited research. Science serves as a forum for discussion of important issues related to the advancement of science by publishing material on which a consensus has been reached as well as including the presentation of minority or conflicting points of view. Accordingly, all articles published in Science—including editorials, news and comment, and book reviews—are signed and reflect the individual views of the authors and not official points of view adopted by AAAS or the institutions with which the authors are affiliated. Science seeks to publish those papers that are most influential in their fields or across fields and that will significantly advance scientific understanding. Selected papers should present novel and broadly important data, syntheses, or concepts. They should merit recognition by the wider scientific community and general public provided by publication in Science, beyond that provided by specialty journals. Science welcomes submissions from all fields of science and from any source. The editors are committed to the prompt evaluation and publication of submitted papers while upholding high standards that support reproducibility of published research. Science is published weekly; selected papers are published online ahead of print.
