Basin and Range Extension created by Tidal Shove of Sierras westward as Earth slows

Basin and Range Extension created by Tidal Shove of Sierras westward as Earth slows
The Earth has its Length of Day increasing some 24 seconds each million years. This is caused by EARTH TIDES (SLOWING THE EARTH), from friction of interaction with the MOON. Consequently, all protrusions such as the high elevation Sierra Mountains incur additional slowing, pushing them westward relative to neighboring lands. The surrounding lower elevation flat lands have less westward movement than the Sierras and continue to move eastward, relatively.

From the above Google Earth photo, it is seen that the transform (lateral shear fault) from Mendocino continues westward from the CA coast until reaching the 41 m.y. kink in the Hawaiian-Emperor seamount chain. This is located at the Kimmei seamount, which is under water and measured by radio-dating drill cores. The transform reaching the 28 m.y. Midway Island is the same as the Garlock fault at the city of Las Angeles:

This is reflected in the occurrence of DEATH VALLEY NM, where the Sierras pull away from the Basin and Range in Nevada- creating extension of B&R across Nevada and part of Utah (AND N-S FRACTURING AND FAULTING IN THE NEARBY MAMMOTH LAKES AND MONOCRATERS AREA. There have been 13 or 14 episodes of extension, about one million years apart.
THIS IS SHOWN IN THE FOLLOWING PHOTO AND DIAGRAM:

ALTHOUGH THE SIERRAS ORIENT NW-SE, THE B&R RANGES ORIENT N-S. THIS RELATES THAT TIDAL EFFECTS- DUE TO THE EARTH SLOWING- ACT DIRECTLY WESTWARD. THE MONOCRATERS AND MAMMOTH LAKES GEOTHERMAL AREA LINE ON A N-S TREND, EVEN THOUGH THE SIERRAS JUST TO THE WEST ORIENT DIAGONALLY TO THIS TREND. PHOTO BELOW SHOWS A YOUNG VENT WHICH HAS BEEN SHEARED BY THE N-S LATERAL MOVEMENTS, IN DEATH VALLEY NM:
