...Götz H. R. Bokelmann; Stefan Baisch Abstract We study the nature of extremely narrow-band signals that appear in typical long-time spectra of seismic recordings. At the German Experimental Seismic System ( GERESS ) array, we observe several of these time-continuous spectral lines. The most...

...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...

...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...

... and T = 500–800 °C using a Griggs-type deformation apparatus. Magnesium germanate is an analog material of magnesium silicate, and the starting material was dried prior to experimentation. Nevertheless, the samples had initially high porosity, and hence a small amount of water (about 200 ppm wt H 2 O...

... the forces on atoms were less than 1 × 10 –4 Ry/Bohr and total energies converged to 1 × 10 –6 Ry. In three separate experimental runs, the germanate olivine samples were compressed to peak pressures of 26, 54, and 105 GPa at room temperature ( Fig. 1 ). The diffraction patterns up to 30 GPa can...

Moreover, a reliable magnitude estimate, in conjunction with a monitoring system that operates continuously and covers a broader area, could potentially provide valuable information and improve the seismic hazard estimates in the region. Figure 3. Examples of experimental...

... using data from the German Experimental Seismic System detected a clear signal at 2.08 Hz and was able to suggest that its source was located near the German-Czech border, although the physical device or devices that generated the signal were not identified. The same study found that the signal...

... in the electronic edition. Seismic monitoring in Ukraine traces back to 1899 when the first seismic station was established in Lviv. Before 1990, prior to Ukraine’s independence, seismological data collection at the national level was managed by the Central Experimental and Methodological Seismological...

The influence of OH content on elastic constants of topaz has not been fully understood, though experimental and theoretical studies have been done on topaz with various OH contents. We thus determined elastic constants...
