Since 2013, the localizations edited by the OGS Bulletin benefit the data exchange with Italian, Slovenian, Austian and Swiss seismological Institutes. Regione Autonoma Friuli Venezia-Giulia, Regione Veneto, Provincie Autonome di Trento e Bolzano, INGV, ARSO (SLO), ZAMG (A) and SEG-ETH (CH) share the seismological data through Antelope Software. Some difference could arise in earthquake location when comparing different bulletins because of different picking and velocity model. Bulletins contain the seismicity occurred in North-East Italy and its surroundings (red polygon on the map).
