Seismological Research Letters (2003) 74 (6): 803–816.
... Experimental Seismic System, known as the GERESS array, is identified in Annex 1 of the Protocol to the Comprehensive Nuclear Test-Ban Treaty (CTBT) as a primary seismic station (PS 19). Since its construction and commissioning in 1991, the performance of this array has been hampered by incidental occurrences...

...V. Schlindwein; K. Koch Abstract Site effects were studied for the individual sites of the 25 elements of the German Experimental Seismic System (GERESS) array based on the traditional spectral ratio (TSR) technique and horizontal-to-vertical ratios (HVRs) for earthquakes and microtremors, commonly...

... uncertainties are about 2° for regional events and about 5° for teleseismic nuclear events. For illustration, we demonstrate performance for Nevada and Tuamotu nuclear tests and for regional events from Poland. Unbiased measurement requires array topography (about 200 m for GERESS ) to be taken into account...

...M. L. Jost; J. Schweitzer; H.-P. Harjes Abstract Since the installation of the 25-element GERman Experimental Seismic System ( GERESS ) array in southeastern Germany in 1990, 36 presumed nuclear tests were recorded by this system: 16 from Nevada, 12 from the Tuamotu Archipelago, 7 from Lop Nor...

...Jan Wüster Abstract Both natural and artificial seismicity is observed in the Vogtland area at near regional distance (180 km) from the GERESS array. This setting offers the opportunity to test various discrimination criteria using a uniform data set of 39 earthquakes and 22 chemical explosions...

.... There is no clear evidence for a negative noise correlation distance at these frequencies. Signal coherence in the same frequency bands proved to be excellent (>0.9) for all regional phases over the 3 km aperture of the test array. The final configuration of the new regional array in the BF area—named GERESS—has...
