Palisades Road, Hayward, Creep 1995-2006 Site map and cross-section For real time data click here user=geo, password=hobo

The mean creep rate 1994-2006 is 4.77 mm/yr. Seasonal thermoelastic signals at this site are large (±2.5 mm) since the instrument is buried beneath a blacktop road surface. Road traffice has no effect on the creep signal. A large steel utility pipe was buried beneath the western end of the creep meter length-standard in September 2006 requiring the removal of a mechanical offset of ≈3mm. The loss of datum is less than 0.5 mm.

The 1994/07 calibrated data (mostly) interpolated to hourly values may be downloaded here . Thermoelastic effects have not been suppressed from these data. The two columns are space delimited date&time (MM/DD/YY HH:MM:SS) , and calibrated dextral slip in mm. Only two significant places of decimals are meaningful. The detrended data show an approximate sinusoidal ±2.5 thermoelastic signal, which after the removal of an annual sine-wave term reduces to a ±1.5 mm residual.
