  <dc:description>&lt;p&gt;Models of the spatiotemporal evolution of earthquake slip, termed finite-fault models,&amp;nbsp;are a critical component of rapid earthquake and tsunami response, earthquake forecasting, seismic ground-motion estimates, and studies of earthquake kinematics. Here, we detail a newly released finite-fault modeling software, Wavelet Inversion for SliP&amp;nbsp;(WISP), in use at the U.S. Geological Survey’s National Earthquake Information Center&amp;nbsp;(NEIC) and available to the public. WISP version 1.1.0 allows inversion of teleseismic body&amp;nbsp;and surface waves, as well as local strong-motion, static and dynamic Global Navigation&amp;nbsp;Satellite System, and satellite imagery (e.g., Interferometric Synthetic Aperture Radar)&amp;nbsp;observations on single or multiple planar fault segments. The software is used in&amp;nbsp;NEIC rapid response of earthquakes &lt;i&gt;M&lt;/i&gt;&lt;sub&gt;w&lt;/sub&gt; ≥ 7, generally resulting in a published model&amp;nbsp;within the first few hours after the event origin time. The rupture location and dimensions are then used as inputs to downstream products to estimate earthquake shaking,&amp;nbsp;predict loss, and model the likelihood of secondary hazards, namely landslides and liquefaction. WISP is also used in research studies to evaluate the characteristics of complex&amp;nbsp;ruptures including multifault ruptures and earthquake doublets, among others. The WISP&amp;nbsp;version 1.1.0 software release is composed of Python-wrapped FORTRAN code to accomplish the inversion procedure. A simple command line interface facilitates ease of use&amp;nbsp;even for those with only a cursory knowledge of Python scripting. WISP version 1.1.0&amp;nbsp;includes a Jupyter Notebook tutorial demonstrating use of the software for modeling&amp;nbsp;the 2015 &lt;i&gt;M&lt;/i&gt;&lt;sub&gt;w&lt;/sub&gt; 8.3 Illapel, Chile, earthquake. In parallel with the tutorial, we demonstrate&amp;nbsp;the typical usage of the WISP software using the &lt;i&gt;M&lt;/i&gt;&lt;sub&gt;w&lt;/sub&gt; 8.3 Illapel earthquake example here.&lt;/p&gt;</dc:description>
