For the same period (2011-2012) and area (45 <= latitude <= 49 and 10 <= longitude <= 17) only the following events are available in the REB bulletin catalogue of the CTBTO IDC:

The integrated Northeast Italy-Austria Seismic Networks Operational System.It consists of 47 seismic stations - a mix of short period, broad band and very broad band ones – in the area of this study: 45 <= latitude <= 49 and 10 <= longitude <= 17

The integrated ZAMG (CTBTO NDC Austria) and OGS bulletin catalogcontains for the years of the test (2011-2012) 6480 events.

The minimum ML magnitude was ML = -2.7

The maximum ML magnitude was ML = 5.0

Map of the NDCs events with ML >= 3.1 missing in the CTBT IDC REB catalogue.

Events number: 43

ML max = 5.0

The average relative location error between IDC REB and NDCs catalogue was 12 km

The average relative magnitude error between IDC REB and NDCscatalogue was 0.5
