"At Lisbon “a sound of thunder was heard underground, and immediately afterwards a violent shock threw down the greater part of that city. In the course of about six minutes sixty thousand persons perished. The sea first retired, and laid the bar dry; it then rolled in, rising fifty feet or more above its ordinary level.” “Among other extraordinary events related to have occurred at Lisbon during the catastrophe, was the subsidence of a new quay, built entirely of marble, at an immense expense. A great concourse of people had collected there for safety, as a spot where they might be beyond the reach of falling ruins; but suddenly the quay sank down with all the people on it, and not one of the dead bodies ever floated to the surface.”— Ibid., page 495. GC 305.1"
"And there were voices, and thunders, and lightnings; and there was a great earthquake, such as was not since men were upon the earth, so mighty an earthquake, and so great."
Both passages describe a cataclysmic event involving thundering and a great earthquake. The EGW passage describes the Lisbon earthquake, which is often seen as a fulfillment of end-times prophecies, including Revelation 16:18.
“The shock” of the earthquake “was instantly followed by the fall of every church and convent, almost all the large public buildings, and more than one fourth of the houses. In about two hours after the shock, fires broke out in different quarters, and raged with such violence for the space of nearly three days, that the city was completely desolated. The earthquake happened on a holyday, when the churches and convents were full of people, very few of whom escaped.”— Encyclopedia Americana, art. “Lisbon,” note (ed. 1831). “The terror of the people was beyond description. Nobody wept; it was beyond tears. They ran hither and thither, delirious with horror and astonishment, beating their faces and breasts, crying, ‘Misericordia! the world's at an end!’ Mothers forgot their children, and ran about loaded with crucifixed images. Unfortunately, many ran to the churches for protection; but in vain was the sacrament exposed; in vain did the poor creatures embrace the altars; images, priests, …
"There were present at that season some that told him of the Galileans, whose blood Pilate had mingled with their sacrifices. And Jesus answering said unto them, Suppose ye that these Galileans were sinners above all the Galileans, because they suffered such things? I tell you, Nay: but, except ye repent, ye shall all likewise perish. Or those eighteen, upon whom the tower in Siloam fell, and slew them, think ye that they were sinners above all men that dwelt in Jerusalem? I tell you, Nay: but, except ye repent, ye shall all likewise perish."
Both passages address the question of whether those who suffer in disasters are necessarily greater sinners than others. Jesus' response in Luke 13:1-5 directly refutes this idea, and the EGW passage, by describing the Lisbon earthquake, implicitly raises the same question, even though it doesn't explicitly answer it. The people's cries of 'Misericordia! the world's at an end!' also reflect a sense of divine judgment, which is a thematic link.
