High-precision Aftershock Locations and Fault Planes of the 2016-2017 Central Italy Sequence

The earthquake catalog includes high-precision hypocenter relocations for 390,334<br> earthquakes recorded during the 2016-2017 Amatrice (Central Italy) <br> earthquake sequence. The relative locations were computed by double-difference inversion of a <br> combination of INGV phase picks and cross-correlation differential <br> times measured from correlated seismograms with correlation coefficients &gt; 0.7. Planes of normal faults (idx=1-5) are derived from PCA analysis of 2 months of aftershock <br> locations in the CAT4 catalog following large events. Surfaces of detachment faults (idx=7-10) are derived from mapping out the location of correlated earthquakes. Citation: Waldhauser, F., Michele, M., Chiaraluce, L., Di Stefano, R., &amp; Schaff, D.
