New borehole array in AfricaMarch 2005Güralp Systems has been chosen to provide the borehole instrumentation for a major new seismic array in Central Africa. | |
Güralp débuts all-in-one borehole solutionMay 2004Güralp Systems is designing a complete seismic station in a borehole for the Swiss Seismological Survey (SED) and ETH Zürich, which combines weak and strong motion sensors to yield an effective dynamic range over 200 dB. | |
Borehole instruments reach the South PoleMarch 2003A Güralp CMG-3TB borehole instrument has been installed in the ‘Quiet Sector’, 8 km from the South Pole, as part of the recently-commissioned SPRESSO (South Pole Remote Earth Science and Seismological Observatory. Initial results show the site to be among the quietest ever measured. | |
