Observatory Seismology
Author: Joe J. Litehiser
Publisher: Univ of California Press
ISBN: 9780520065826
Category : Science
Languages : en
Pages : 400
Book Description
The first effective seismographs were built between 1879 and 1890. In 1885, E. S. Holden, an astronomer and then president of the University of California, instigated the purchase of the best available instruments of the time "to keep a register of all earthquake shocks in order to be able to control the positions of astronomical instruments." These seismographs were installed two years later at Lick Observatory on Mt. Hamilton and at the Berkeley campus of the University. Over the years those stations have been upgraded and joined by other seismographic stations administered at Berkeley, to become the oldest continuously operating stations in the Western Hemisphere. The first hundred years of the Seismographic Stations of the University of California at Berkeley, years in which seismology has often assumed an unforeseen role in issues of societal and political importance, ended in 1987. To celebrate the centennial a distinguished group of fellows, staff, and friends of the Stations met on the Berkeley campus in May 1987. The papers they presented are gathered in this book, a distillation of the current state of the art in observatory seismology. Ranging through subjects of past, present, and future seismological interest, they provide a benchmark reference for years to come. The first effective seismographs were built between 1879 and 1890.

Spectral Analysis and Statistical Properties of Microseisms at Norsar
Author: Eivind Rygg
Publisher:
ISBN:
Category : Microseisms
Languages : en
Pages : 44
Book Description
Below 0.7 cps the seismic noise recorded by the short period seismometers at NORSAR (Norwegian Seismic Array) is generally dominated by sources in the Atlantic and on the Norwegian coast. When strong low pressure areas are observed outside the coast, the noise has a dominating direction of propagation from the low, and a velocity generally in the range 3-4 km/sec. A low in the Baltic Sea has been found to contribute more to the noise at higher frequencies than the Atlantic sources, its influence extending to lower frequencies as the low moves towards the array. Strong local winds have been found to have little influence in the microseismic range. The noise coherence between sensors is some times much higher in the direction of dominating noise propagation than in other directions. This seems to happen when the noise level is high and when the lows are close to the coast. From the distribution of the sample variances it is assumed that the noise is stationary within half-hour intervals used in the noise analysis. The noise predictability has a maximum during periods with high microseismic activity. (Author).
