workshop was organised on the seismic array analyses programmes.
For F-k, the most sensitive parameters are associated with the reliability range of each seismic array (Figure 2(a)) because they depend on distance (D), wavelength ([lambda]), and number of waves (K), where Kmin and kmax, given in a two-dimensional space Kx and Ky (Figures 2(b) and 2(c)), define the greatest and least contribution of energy to propagating waves.
With Sunday's large North Korean blast, NORSAR, short for the Norwegian Seismic Array, a research group based in Kjeller, noted that global shock waves alone provide insufficient information to determine if the detonation was a true hydrogen bomb, as the North declared."But we can say in general," the group added,"that the credibility of the claim increases with increasing explosive yield." It said other evidence, such as leaks of radioactivity from the underground test site, might solve the riddle of the bomb type in the weeks to come.
A beamforming method (62, 65, 66) with a dense seismic array can feasibly be used to locate the sources of microseisms (67, 68) and seismic hum.

And Hurricane Katrina in 2005, Koper adds, "was recorded by a seismic array in California, and they could track the path of the storm remotely using seismometers."

Recently, Xi Engineering has attracted worldwide attention for its work on wind turbines in South West Scotland, to prevent them interfering with the MoD Eskdalemuir Seismic Array which monitors illegal nuclear testing.
Figures 2.1, 2.2 and 2.3 show a preliminary analysis of the location of the induced micro-earthquakes based on approximately 750 micro-seismic events of the more than 4000 events detected by the extensive passive seismic array installed across the Paralana site.
The ARC seismic array at Karnal, specifically designed to pick up underground nuclear tests, too, came to the conclusion that the thermonuclear test was a " fizzle." The government was thus provided three sets of reports-- a 50- page report by the DRDO based on the on- site instrumentation that it had set up, a detailed report based on the seismic readings picked up by the ARC in its various facilities, and a report by the DAE based on some seismic instruments it had brought onsite at the last minute.
RESIS II (Earthquake Risk Reduction in Guatemala, El Salvador and Nicaragua, with regional cooperation to Honduras, Costa Rica and Panama) is a project which aims to continue the sequence of cooperative projects that the Norwegian geoscientific research foundation NORSAR (NORwegian Seismic ARray) has with Central America.
