I moved the seismometer to a new hole, 20 m +Y of the EY station. I did this because I made an estimate that suggested that the wind was causing ground tilt through Bernoulli forces at the level of the tilt signal we were seeing from the buried seismometer (as judged by comparing Z, which is insensitive to tilt, to X and Y). I thought that these forces would be lower if the seismometer was up-wind of the building instead of beside the building where there was building induced turbulence. This 20m +Y location seems better than the 20m location +X of the building, and is generally a factor of 2 or more below the building seismometer in the tilt band below 0.1 Hz. All plots are a comparison of the buried seismometer to the SEI GND seismometer in the building. The red traces are the inside seismometer. The first plot is for an average of 14 MPH, the second for an average of 23 MPH. We havent had higher winds yet since I buried the seismometer. I believe that Jim is trying out the new blend filters on this buried seismometer.
