The hydroplate theory is a model concerning events related to the global flood recorded in Genesis. For more information on the theory itself, see the following:
As with other models, there have been criticisms and questions raised regarding the theory. Edward Isaacs published an article questioning the theory’s proposed formation mechanism for the Pacific trenches. Isaacs’s article can be obtained here: https://creation.com/images/pdfs/tj/j32_3/j32_3_58-63.pdf
Below is Bruce Armstrong’s letter to the editor [published in J Creation 33(2):61–62, 2019] in rebuttal to Isaacs’s article. It is presented here with Armstrong’s permission. Spelling, punctuation, and styles used in the original publication have not been edited.
I am responding to Edward Issacs’ paper: Hydroplate Theory - problems for trench formation in the Pacific Basin, J. Creation 32(3):58-63, 2018.
First, I would like to thank Issacs for his brief summary of Walt Brown’s Hydroplate Theory (HPT), which is mostly correct. However, Issacs’ entire paper is based on his incorrect claim that HPT requires a trench that is antipodal to the Mid-Atlantic Ridge (MAR) system. As this letter will show, Walt Brown clearly illustrates in his book In the Beginning that this system is not part of HPT.
Issacs begins building his case by quoting passages from pages 155 and 159 of Brown’s book. He claims that they "identify two major locations for trench formation". He then claims that the trenches within the Pacific Plate must be antipodal to the MAR.
Brown simply says that much of the Pacific plate, centred around a position opposite the middle of the Atlantic floor, sank and cracked, forming "fractures in millions of places". These fractures are the same ‘trenches’ referred to in the earlier quote. He does not claim that this subsidence resulted in a major trench system being formed in exact antipodal positions to the Mid-Atlantic Ridge (MAR) as Issacs proposes. In fact, Brown does not even mention the MAR in this context, but merely indicates the centre of the Atlantic floor. Brown goes on to explain that the deepest trenches opened up primarily around the west, north and east edges of this sinking plate, exactly as one would expect if a large three-sided ‘flap’ of the crust subsided and then later was lifted. This is why Brown has no illustrations showing a Central Pacific Trench system and Issacs has had to create his own graphics for his Figures 6, 7 and 8. Issacs could have easily seen that he had misinterpreted Brown by examining Brown’s own graphic (figure 83) on the previous page (p. 154), as shown below.
Figure 83: "Trenches of the Western Pacific. Sixteen ocean trenches are concentrated in the western Pacific. Four others are located elsewhere... . The white cross marks the centre of this concentrated trench region... . Why is the centre of this trench region almost exactly opposite the centre of the Atlantic Ocean, both in latitude and longitude?" (Mountain High Maps © 1992-2019 Digital Wisdom Inc.)
