Abstract:  Surface vault broadband seismometers have typically yielded good results on the vertical, but have been unreliable and noisy on the horizontal.  There are several reasons for this issue, including inherent problems with surface tilt noise and thermal stability.  A comparison study was undertaken between the highest performing vault seismometers and a new broadband Posthole seismometer in a downhole installation, at different depths and in various environments at stations in North America ranging from remote locations in Alaska to a noisy urban area.  In the remote and urban studies, a spectral analysis was conducted and PSD plots were generated, the results of which will be provided in detail in the paper.  This paper will discuss all of the results from these installations and the various installation methods used at these locations.
