Internal consistency alert, from 2 Nephi 26:
5 And they that kill the prophets, and the saints, the depths of the earth shall swallow them up, saith the Lord of Hosts; and mountains shall cover them, and whirlwinds shall carry them away, and buildings shall fall upon them and crush them to pieces and grind them to powder.
6 And they shall be visited with thunderings, and lightnings, and earthquakes, and all manner of destructions, for the fire of the anger of the Lord shall be kindled against them, and they shall be as stubble, and the day that cometh shall consume them, saith the Lord of Hosts.
Compare to 3 Nephi 8:5-11
5 And it came to pass in the thirty and fourth year, in the first month, on the fourth day of the month, there arose a great storm, such an one as never had been known in all the land.
6 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.
7 And there were exceedingly sharp lightnings, such as never had been known in all the land.
8 And the city of Zarahemla did take fire.
9 And the city of Moroni did sink into the depths of the sea, and the inhabitants thereof were drowned.
10 And the earth was carried up upon the city of Moronihah, that in the place of the city there became a great mountain.
11 And there was a great and terrible destruction in the land southward.
Also compare 1 Nephi 12:4
4 And it came to pass that I saw a mist of darkness on the face of the land of promise; and I saw lightnings, and I heard thunderings, and earthquakes, and all manner of tumultuous noises; and I saw the earth and the rocks, that they rent; and I saw mountains tumbling into pieces; and I saw the plains of the earth, that they were broken up; and I saw many cities that they were sunk; and I saw many that they were burned with fire; and I saw many that did tumble to the earth, because of the quaking thereof.
