Hydroplate Theory - Problems for Trench Formation in the Pacific Basin

September, 2020


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. 1

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.)

The Mystery of 90 East Ridge

September, 2019

90 East Ridge

Fig. 1 - 90 East Ridge indicated by arrows; the Himalayas are circled. 1


  1. Why is there a 3,000-mile-long, underwater ridge 2,3 in the Indian Ocean?
  2. Why does it have a north-south orientation?
  3. Why is it south of and pointed toward the Himalayas?
  4. How did it form?

We will explore these questions in this article.


One clue is that directly north of the ridge is the most massive mountain range in the world - the Himalayas. We also note that the Tibetan Plateau is also present just north of the Himalayas. This plateau contains much elevated mass also. The average height of this plateau is 14,800 feet, and it stretches 1,600 miles east-west and 620 miles north-south. This is a lot of mass directly north of the ridge!

Another clue is the North-South orientation of the ridge.

Creation News

May, 2018

May’s newsletter is dedicated to recent findings in science related to creation. It reflects the author’s interests and is by no means comprehensive or exhaustive. 

Jonathan Sarfati, Russ Humphreys, and John Sanford Are Coming to the Triangle This Fall

These three men are some of the finest creation scientists alive today! Plan now to take advantage of these rare opportunities.

Jonathan Sarfati of Creation Ministries International and author of Refuting Compromise will be visiting the Triangle this September. He will be speaking at Cornerstone Baptist Church on Sunday morning September 23 at 9:30 PM. On Sunday night he will be at Friendship Baptist Church. On Monday night, September 24, the goal/plan is to get him on the NC State campus. On Tuesday night, September 24, he will be back at Cornerstone at 7:00 PM. Then on Wednesday night, September 25, he will be at Community Baptist Church in south Garner. Mark your calendars! Tell your friends!

Mammoth Mystery

January, 2012


Figure 1 - Museum exhibit of a mammoth

Mammoths pose a mystery to science. How did they get frozen? The answer is not as simple as you might think. Normal cold weather would not freeze them quickly enough to preserve them as well as they are found. The temperature had to drop drastically, in only a few hours, to -150° F or lower! Based on the range of places where they are found, this had to be a widespread, not just a local, phenomenon.

This article will explore the mystery of mammoths, and analyze several theories trying to explain the facts. (This summary is based primarily on the book In the Beginning, by Walt Brown, PhD. 1)

Implication of Finding Noah's Ark

October, 2011

Even though Noah’s Ark has not been discovered yet, we have the Word of God that records in the Hebrew book of B’resheet (Genesis) that the Ark rested in the Mountains of Ararat. This emplacement implies an altitude high above the current sea level, the result of the catastrophic and universal Deluge, that in biblical chronology happened about 4400 years ago. This universal flood refaced the earth’s surface (mountains, oceans, rivers, valleys, caves, fossils, sedimentary layers, volcanoes, etc.). Furthermore, Noah, his seven family members, and pairs of land dwelling animals that were carried in the Ark survived the catastrophe. No water dwelling creatures or insects were included in God’s rescue venture.

We do not know with certainty what happened to the Ark afterwards. The Ark may have disintegrated or rotted, or perhaps the lumber was reused, or it may still exist intact somewhere on those mountains.

Scoffers have mocked the Bible entirely. The secular theory of evolution has its own version of the origin of life that allegedly happened millions of years ago. Several branches of science have been developed under this secular but also religious worldview.

How Did This Happen?

February, 2011

The Grand Canyon

The Grand Canyon is probably the most famous geologic formation in the world. It is 216 miles long, 1 14–18 miles across, and about a mile deep. The first question most visitors express is, “How did this happen?” Many geologists have tried to answer this question and have proposed different theories as to how the canyon was formed.

Geologists saw the power of moving water through catastrophic failures of dams that breached. In 1889 the Johnstown flood and the 1976 Teton Flood in Idaho, breached dams caused loss of life and showed quick catastrophic geological events. Unfortunately, in geology, invoking catastrophes violates a “sacred rule,” any explanations should involve only processes we see today. This assumption, known as uniformitarianism, still underlies most geological thinking today.

Catastrophic Geologic Evidences in Ecuador - Part 1: Fossil Formations

October, 2008

Figure 1 - Location 1: Las Peñas: The coast line is formed with thousands of thin colorful layers of sedimentary rock (Figure 2), exposed to erosion by the tides of the Pacific Ocean. These visible layers are just the tip of what probably extend thousands of feet below sea level.

In December 6, 2006 I had the opportunity to arrive in Ecuador, South America (Figure 1) for a month and a half trip. Mainly my family was looking to have vacation time, but all turned out to be filled up with adventure and discovery. After being involved with creation science, suddenly my eyes started catching sites of evident catastrophism—so the adventure began. In this article, I will present the first finding at Las Peñas, located northwest of the country not too far from Atacames Beach. 

Bits and Pieces from the Earth Sciences

Unfossilized soft tissue from bone of Tyrannasaurus rex

A: The arrow points to a tissue fragment that is still elastic. How could elastic tissue like this have lasted for 65 million years?

B: Another instance of “fresh appearance”.

C: Regions of bone showing where the fibrous structure is still present, compared to most fossil bones, which lack this structure.

This past January North Carolina State University held a dedication for a new wing of the Earth Sciences building, which, naturally, houses the geology department. Being an alumnus of the geology program (1975) I received an invitation to attend. When I saw that one of the featured speakers was to be Dr. Mary Schweitzer, the discoverer of red blood cells and soft collagen (a protein found in most tissues of living organisms) in a fossilized Tyrannosaurus rex bone, I could not miss it.
