Thrust meters

Thrust-bearing-load meters for protection against excessive loading are available on thrust bearings, and automatic thrust control, which functions by controlling the pressure behind a balancing drum, also is available. 

In intermediate and larger sizes the thrust bearing problem requires more attention, but it has been effeetively solved reeently by the introduetion of the thrust foree meter and thrust foree adjustment valve, deseribed earlier.

There are deeper caves that contain stalactites and stalagmites that could only have formed when the cave was air-filled. Using mass spectrometric UATh dating, Richards et al. (1994) measured sea level low stands down to 50 meters below present sea level. The last extensive thrust of the Wisconsinan ice sheet at about 20 ka is clearly shown. Speleothems recovered from a cave on Andros Island, Bahamas at —45 meters was dated at 139 - 160 ka, showing that sea level must have been at least this low at that time...

The creation of Time-Limited Dispatch (TLD) followed the introduction of Full-Authority Digital Electronic Control (FADEC) systems to commercial aircraft in the 1980s. FADEC systems replaced hydromechanical control (HMC) systems and took over the role of governing engine thrust from the start of fuel metering to the point of fuel shutoff. When FADEC systems were introduced it was the first time that HMC systems would not be available to pilots in the event of electronic system failure (Larsen Horan 2002). 

As discussed above, the earthquakes were not caused by active fault movements. The thrust movements of the fault solid rock walls were passively caused by the uplifting of powerfully expanding and migrating natural gases in the faults. The passive thrust movements could be only a few tens meters. They could not push, vibrate or force the seawater of thickness from three to six thousand meters to form the extremely large tsunami waves.
