Friday sesmic forecast
ERDF expects to operate the pit through the day today.  Hanford container hauling will occur on day shift and swing shift today.  There's no indication that ERDF will operate tomorrow, 10/25.

The attached plot from last week shows a couple of interesting features.  1)  The Wednesday 10/15 1-3Hz noise doesn't show the typical truck-induced bimodal day shift/swing shift appearance.  The Wednesday noise instead is just a single hump that rises above the other weekday levels.  The Hanford haulers were mostly shut down on 10/15 due to high winds.  Wednesday noise appears to come from winds at LHO.  The 0.3-1Hz trace, which isn't very sensitive to trucks, tends to corroborate this.  2) On Saturday 10/18, the trucks did not carry containers back and forth to ERDF, but crews at the pit emptied containers and ran their bulldozers and compactors until roughly noon.  The plot provides the somewhat rare opportunity to see pit noise in the absence of transportation noise.
