20061104 report

CW/CCW inclinometry


Inclinometry was performed as follows:

    Datasets  El Dirn     HST     mean leg temperatures   Humidity
                          start     start   middle   end       %
  ( 20061101  89  cw      04:18      -         -      -
    20061101  89 ccw     ~07:00      -         -      -          )
    20061104  89  cw      05:18      -         -      -      
    20061104  89 ccw     ~08:00      -         -      -        

Data is recorded from the 3 active inclinometers only: there is no strain gauge data, for instance. Engarchive has been unavailable since the earthquake on 20061015 - so no leg temperatures are recorded.

  • The differences between the (CW) model derived from these new data and the previous model of 01 Nov are shown below :

    The observed changes in the (CW) track model are small, with rms scatter in the differences in (F1,F2,F3) of (0.28", 0.31", 0.37").

    The CW-CCW differences are shown below:

    These are similar to those seen most recently. A hybrid track model was generated and installed at HST 11:05 on 09 Nov 2006.
