The earthquake was located by: U.S. Geological Survey (USGS).
Search earthquakes: Any within 30 km radius
The values of hypocentral coordinates and magnitude may be revised at a later time as more information becomes available.
No Italian municipalities within 20 km distance.
No Italian municipalities within 100 km from the epicenter with at least 50000 inhabitants.
These three maps show the results of the analysis using the software ShakeMap designed to provide the level of ground shaking experienced in a region using the data recorded by seismometers and strong motion instruments and seismological information regarding the attenuation of the wavefield with distance and the site characteristics. The Shakemaps are determined for research purposes to provide fast estimates of the level of ground shaking produced by the earthquake. The maps are calculated automatically and updated as more data become available. See http://shakemap.ingv.it for additional information. The black star indicates the epicenter. The triangles show the accelerometric and velocimetric stations used in the calculation, colored according to the recorded shaking.
