Plots

Plot showing NA-fixed data (All data)

These plots depict the North, East and Up components of the station as a function of time. More detailed explanation »

Dashed vertical lines show offsets (when present) due to:

  • Green – antenna changes from site logs
  • Red – earthquakes
  • Blue – manually entered

These results are preliminary. The station positions are unchecked and should not be used for any engineering applications. There may be errors in the antenna heights. The velocities are very dependent on the length of the span of observations. The presence of outliers (errant observations) sometimes contaminates the velocities.
