Samuel the Lamanite’s prophecy of destruction came to pass in the “the thirty and fourth year, in the first month, on the fourth day of the month.” The beginning of the description of the destruction emphasized that it was greater than any in that land had known before:

There arose a great storm, such an one as never had been known in all the land. And there was also a great and terrible tempest; and there was terrible thunder, insomuch that it did shake the whole earth as if it was about to divide asunder. And there were exceedingly sharp lightnings, such as never had been known in all the land. (3 Nephi 8:5–7)

Surely any real-world location for the Book of Mormon should be able to demonstrate that the destructive events catalogued in Third Nephi could have taken place in that location.

The Heartland’s Destructive Earthquake

As Neville approached this question, he wrote:

What kind of terrain can experience a calamity in which the “whole face of the land” changes, yet it remains recognizable centuries later?

The term “face of the land” suggests the changes affected the face, or surface, of the land but left major features intact. What the text describes is not volcanic action, or a shift in the earth’s crust that formed or destroyed huge mountains. Instead, the text describes an earthquake accompanied by a major shift in alluvial lands.

One place in the world where exactly this has occurred is along the Mississippi River.[1]

Before discussing his evidence, it must be noted that the entire argument is built upon a thesis Neville had already decided upon. Without saying why it is not volcanic action, he asserts that it must be an earthquake and a flooded river. By establishing that definition, he can then suggest that only the Mississippi River has shown conditions that fit. Pretty much any hypothesis is supported by defining the problem to fit the hypothesis. In this case, does the suggestion of an earthquake and an alluvial plain fit the descriptions in the text?

Third Nephi 8: 6 requires a tempest. Neville uses one of the 1828 Webster’s dictionary definitions to restate tempest as a tornado. This allows him to have a wind event that does periodically occur in that region.[2] That much is reasonable.

An obvious aspect of the descriptions of destruction is the shaking of the earth. Neville proposes:

The largest earthquakes known to have struck what is now the continental United States were the New Madrid earthquakes of 1811-1812. New Madrid is located along the Mississippi River, about 170 miles south of St. Louis on the border between Missouri and Tennessee. The earthquakes had a magnitude of around 8.0 and the impact was felt as far away as Washington, D.C.”[3]

He also indicates that similar magnitude earthquakes occur around every 500 years along the New Madrid fault.[4]

One of the things that Neville does not address is the problem of time. Three Nephi 8:19 reports:

And it came to pass that when the thunderings, and the lightnings, and the storm, and the tempest, and the quakings of the earth did cease—for behold, they did last for about the space of three hours; and it was said by some that the time was greater; nevertheless, all these great and terrible things were done in about the space of three hours—and then behold, there was darkness upon the face of the land. (3 Nephi 8:19)

This is an important omission if Neville’s quakings are truly from an earthquake. A blog post from the University of Utah Seismograph Stations answers a question about how long earthquakes last: “Generally, only seconds. Strong ground shaking during a moderate to large earthquake typically lasts about 10 to 30 seconds.”[5] The longest official earthquake on record was the 2004 Sumatran-Andaman earthquake which lasted eight to ten minutes.[6] Neville does not explain the discrepancy between perhaps ten minutes and three hours.

Mesoamerica and Volcanic Activity

The reason that Neville introduced his version of the destructions with the statement that it was not due to volcanic activity is precisely because volcanic activity is a prominent explanation for all the facets of the destructions listed in Third Nephi. It is important to note that at least three degreed geologists have written about the destructions in Third Nephi, and all three agree that volcanic activity is the best explanation.[7] Bart Kowallis specifically noted:

The 3 Nephi 8 account cannot be explained solely as a massive earthquake or storm, for neither of these natural disasters can account for all the features described. All of the features of the account can, however, be explained by a specific type of natural phenomenon occurring only in certain geologic settings—an explosive eruption, similar to the eruption in Papua New Guinea and to the eruption on Santorini.[8]

Of interest for the Mesoamerican setting for the Book of Mormon is that the presence of active volcanoes is not limited to just the events in Third Nephi. Jerry Grover suggests that the story of how the brothers, Nephi and Lehi, were freed from a prison in the land of Nephi by an event plausibly involving volcanic activity. After recounting the story, Grover writes:

The other events that occurred considered together have all the hallmarks of a mild volcanic eruption, which would typically include an earthquake corresponding with the start of the eruption, and then a series of mild earthquakes of similar size spaced over the period of the eruption.[9]

The three geologists all provide important information, the details of which I will not attempt to provide. I will quote part of Jerry Gover’s conclusion to his book on the topic:

Another goal of the endeavor was to analyze what the Book of Mormon itself actually says and apply it to the known geology of the Isthmus of Tehuantepec, independent of any of the geographic models, and determine if any definitive results can be derived with regards to Book of Mormon events. Although scientists are reticent to use the word ”proven” there are certain statements that can be made that are very close to the “proven” standard.

  • A volcanic eruption occurred as part of the 3rd Nephi destruction.
  • A volcanic eruption alone cannot account for all of the destruction in 3rd Nephi; the destruction necessarily involved a regional earthquake.
  • Based on current data, a regional earthquake and one volcano and their after-effects can account for all of the destruction in 3rd Nephi, with the exception of the city of Jerusalem, which appears to be a local event.
  • The primary regional earthquake occurred on the Veracruz fault system
  • The primary volcano involved is indicated to be the San Martín volcano based on its position in the Isthmus and on the Veracruz fault system, and the eruption need not have exceeded a 4 on the VEI explosivity scale.[10]
  • Conclusion

    The explanations for the destructions in Third Nephi are dramatically different for the two models. The difference is necessitated because there is no adequate volcanic activity in the Heartland and therefore something else must be used to explain the described destructions. While there are a few of the elements of the destruction that can be explained by an earthquake along the New Madrid fault, the descriptions are consistent with earthquakes, but not with the Book of Mormon description for how long the quakings lasted.

    For the Mesoamerican model, on the other hand, three professional geologists insist that volcanic activity had to be involved. This is an important disqualifying requirement for the Heartland model. First, the requirement was established by qualified geologists. Second, the whole set of requirements cannot be placed in the Heartland.

    Not only does the Mesoamerican model fit the entirety of the requirements, but Grover has presented evidence for a specific volcano that erupted in the approximate timeframe as the destructions in Third Nephi and which was of a type to fit the requirements. According to geologists, Third Nephi is at home in Mesoamerica, but the descriptions are foreign to the Heartland model.
