Evaluation of the Impact of Potentially Compromised Stations on the Localization of Seismic Events

Riassunto

This study analyzes data from a Local Seismic Network affected by documented random time synchronization errors, aiming to develop correction strategies to improve earthquake location accuracy, particularly for moderate to small events. The work focuses on optimizing data usage in hypocentral locations and focal mechanisms in a seismically active area where the Italian National Seismic Network (RSN) has uneven station coverage. With this aim, 15 seismic events recorded by the local Rete Sismica Abruzzo (RSA) and RSN between 2007 and 2016 in the central Apennines were selected. First, we assess the effectiveness of...
