Micah 1:4

"And the mountains shall be melted under him, and the valleys shall be cleft, as wax before the fire, as waters that are poured down a steep place."

The geophysical disturbance of the whole earth is repeatedly mentioned in both the Old Testament and the New Testament as accompaniments of the final judgment day. See Revelation 6:14ff, 11:19,16:17-21, etc. The mention of such phenomena here definitely indicated that the judgment about to be executed against Samaria and Jerusalem is typical of that ultimate judgment upon all mankind, hence the propriety of demanding that "all nations" hear it (Micah 1:2). Some commentators find a reference in these verses to "a great storm"; and it is certain that the "clouds of heaven" shall be present on that occasion (Matthew 24:30). "The description of God's advent to judgment is founded on the idea of a terrible storm and great earthquake, accompanied by volcanic eruptions";[16] but, to be sure, it is impossible to tell if such a description is literal, metaphorical of even greater terrors, or both.
