Centroid Moment Tensor solutions for the earthquake dataset of the project IMAGINE_IT

<p>The project IMAGINE_IT (PI Dr. Dimitri Komatitsch) received 40 million&nbsp;CPU-hours&nbsp;on the Tier-0 GENCI/TGCC CURIE supercomputer as a winner of the&nbsp;9th PRACE consortium call (2014).&nbsp;</p> <p>The awarded computational resources allowed us to construct a new 3D tomographic model for the Italian lithosphere,&nbsp;<em>Im25</em>,<em>&nbsp;</em>by combining spectral-element three-dimensional wavefield simulations and an adjoint-state method.</p> <p>To obtain the final model <em>Im25,&nbsp;</em>we performed 25 adjoint tomography iterations. Moreover, two&nbsp;additional&nbsp;source inversion iterations have been performed&nbsp;in order to improve the earthquake source parameter estimates and reduce the misfit between observed and synthetic seismograms: one inversion using the 3D wavespeed model considered as starting model of the tomographic procedure, and one inversion for the improved wavespeed model at iteration 12 (<em>Im12</em>).&nbsp;</p> <p>The presented table contains the Centroid Moment Tensor&nbsp;parameters&nbsp;of the163 earthquakes considered in the IMAGINE_IT project&nbsp;for: the initial&nbsp;(Time Domain Moment Tensor; http://terremoti.ingv.it/)&nbsp;source solution based on a 1D wavespeed model (iter=0), the source inversion solution with the starting 3D wavespeed model (iter=1), and the source inversion solution with model <em>Im12</em> (iter=2). <strong> </strong></p>
