Did Ellen White predict that New York City would be destroyed by a tidal wave?
No. She protested such assertions. These were false teachers who were deceiving the people and causing her to be falsely accused.
Revelation 18:1 "And after these things I saw another angel come down from heaven, having great power; and the earth was lightened with his glory. 2 And he cried mightily with a strong voice, saying,
Babylon the great is fallen, is fallen, and is become the habitation of devils, and the hold of every foul spirit, and a cage of every unclean and hateful bird. 3 For all nations have drunk of the wine of the wrath of her fornication, and the kings of the earth have committed fornication with her, and the merchants of the earth are waxed rich through the abundance of her delicacies."
Revelation 18:8 "Therefore shall her plagues come in one day, death, and mourning, and famine; and she shall be utterly burned with fire: for strong is the Lord God who judgeth her. 9 And the kings of the earth, who have committed fornication and lived deliciously with her, shall bewail her, and lament for her, when they shall see the smoke of her burning, 10 Standing afar off for the fear of her torment, saying, Alas, alas, that great city Babylon, that mighty city! for in one hour is thy judgment come."
Acts 20:29 "For I know this, that after my departing shall grievous wolves enter in among you, not sparing the flock. 30 Also of your own selves shall men arise, speaking perverse things, to draw away disciples after them."
"Since the San Francisco earthquake, many rumors have been current regarding statements I have made. Some have reported that while in Los Angeles, I claimed that I had predicted the San Francisco earthquake and fire, and that Los Angeles would be the next city to suffer. This is not true. The morning after the earthquake, I said no more than that “the earthquakes will come; the floods will come;” and that the Lord’s message to us is that we shall “not establish ourselves in the wicked cities.” {RH July 5, 1906, par. 11}
"Not many years ago, a brother laboring in New York City published some very startling notices regarding the destruction of that city. I wrote immediately to the ones in charge of the work there, saying that it was not wise to publish such notices; that thus an excitement might be aroused which would result in a fanatical movement, hurting the cause of God. It is enough to present the truth of the Word of God to the people. Startling notices are detrimental to the progress of the work." {RH July 5, 1906, par. 12}
Under date of August 9, 1903, I further wrote regarding this sensational report: {RH July 5, 1906, par. 13}
“How comes the word that I have declared that New York is to be swept away by a tidal wave? This I have never said. I have said, as I looked at the great buildings going up there, story after story, ‘What terrible scenes will take place when the Lord shall arise to shake terribly the earth! Then the words of Revelation 18:1-3 will be fulfilled.’ The whole of the eighteenth chapter of Revelation is a warning of what is coming on the earth. But I have no light in particular in regard to what is coming on New York, only that I know that one day the great buildings there will be thrown down by the turning and overturning of God’s power. From the light given me, I know that destruction is in the world. One word from the Lord, one touch of his mighty power, and these massive structures will fall. Scenes will take place the fearfulness of which we can not imagine." {RH July 5, 1906, par. 14}
“But I have sent cautions to the brethren working in New York, saying that these flaming, terrifying notices should not be published. When my brethren go to extremes, it reacts on me, and I have to bear the reproach of being called a false prophet...." {RH July 5, 1906, par. 15}
