Description:
The knowledge of coseismic deformations due to earthquakes represents the
fundamentals on which studies on seismic cycle and fault source mechanism are based on.
Geodetic methods, in particular the recent developments of GNSS monitoring, are the only
onescapable of providing the displacements of reference sites due to the occurrence of significant
seismic events. Usually the detection of seismic offsets is done by comparing coordinates
estimated before and after the earthquake. Here, considering the test case of the 30
October, 2016 central Italy seismic event, we show that it is possible to achieve such offsets
also in real-time through the application of the new functionalities of the VADASE
(Variometric Approach for Displacements Analysis Stand-alone Engine) approach. The
comparison between the seismic offsets coming from the two approaches (static and realtime)
is shown and discussed; the mean overall agreement is at the level of about half centimetre.
