Data Sets for "Moment tensors of ring-faulting at active volcanoes: Insights into vertical-CLVD earthquakes at the Sierra Negra caldera, Galápagos Islands" (Sandanbata et al., submitted to JGR - Solid Earth)

We conduct moment tensor (MT) inversion for the 2005 earthquake at the Sierra Negra caldera, the Galapagos Islands. For the inversion, we assumed different centroid locations in 3D space, i.e., on the x–y (longitude-latitude) plane at a depth of 2.5 km below the solid surface, and the x–z (longitude–depth) plane along a latitude of 0.83°S across the Sierra Negra caldera. Data Sets S1 and S2 contain MT solutions obtained by the MT inversion with a constraint of zero trace; those solutions are used for Figure 7 in "Main Text". Data Sets S3 and S4 contain MT solutions obtained by the MT inversion with constrains of zero trace and zero <em>DS</em> component (\(M_{r\theta}=M_{r\phi}=0\)); those are are used for Figure S1 in "Supporting Information". For the detailed methodology and data, see Section 3 in "Main Text" and Text S1 in "Supporting Information" of our manuscript.
