NEar-Source Strong-motion flatfile (NESS), version 1.0

The Near-source strong-moton flatfile (named NESS) is a parametric table related to worldwide earthquakes containing high-quality metadata and intensity measures (IMs) of
engineering interest. The table collects reliable information about event sources, such as geometries and rupture mechanisms that are necessary to model near-source effects
for engineering seismology and earthquake engineering applications. The accelerometric records are manually and uniformly processed, and the associated information is fully
traceable. NESS consists of about 800 three-component waveforms relative to 700 accelerometric stations, caused by 74 events with moment magnitude larger than 5.5 and
hypocentral depth shallower than 40 km, with Joyner–Boore distance up to 140 km. Ground-motion data are selected to have a maximum source-to-site distance within one
fault length, defined through seismological scaling relations.
