Data for the seismic sequence timeline are originally from the ISIDe database (http://iside.rm.ingv.it), developed by the National Center for Earthquake at INGV Rome. The focal mechanism of the main shocks are from the RCMT database (http://www.bo.ingv.it/RCMT/searchRCMT.html), INGV Bologna. Further layers from other research groups are being progressively developed: * Shakemap * macroseismic survey includes 360-degree panoramics samples * coseismic migrations measured by gps stations * historic seismicity DBMI08 database * Seismic Faults DISS 3.04 database Full references and credits for data found in each of these layers is given in the corresponding KML descriptions. The earthquake events dataset are time-stamped and positioned at altitudes proportional to the (inverted) depth of occurrence. Seismic events with magnitude above 4.0 are displayed with the moment tensor graphical re
