What did the Bible say about volcanic eruptions?

 

Recently, the Anak Krakatau volcano erupted in Indonesia in early September 2026.

Eruption Details

✓ Location: Sunda Strait, between Java and Sumatra

✓ Start Date: September 4–5, 2026

✓ Impact: Sent ash plumes up to 50,000 feet, causing the temporary closure of eight airports including Jakarta's Soekarno-Hatta International Airport and disrupting flights for thousands of passengers. Other Indonesian volcanoes like Semeru, Mount Ibu, and Lewotolok also experienced activity around the same period.

The literal word "volcano" or "eruption" does not appear in the Bible, but scripture frequently uses powerful thermal, seismic, and volcanic imagery to describe God's presence, judgment, and end-times prophecy.

Volcanic Imagery and Divine Presence

Many passages describe mountains acting in ways that mirror active volcanoes, such as smoking, shaking, or melting when God draws near:

✓ Mount Sinai: Described as covered in smoke, blazing with fire to the heavens, and trembling as the Lord descended upon it (Exodus 19:18; Deuteronomy 4:11).

Some scholars debate whether this was literal volcanic activity or profound storm/theophany imagery.

✓ Melting Mountains: Poetry in the Psalms and prophetic books uses the image of mountains melting like wax or flowing like fire:

"The mountains melt like wax before the Lord..." — Psalms 97:5

"The mountains melt beneath his feet and flow into the valleys like wax in a fire..." — Micah 1:4

"Oh, that you would burst from the heavens and come down, that the mountains would quake before you!" —  Isaiah 64:1

✓ Smoking Hills: "He who looks at the earth, and it trembles, who touches the mountains, and they smoke." — Psalm104:32

Judgment and Prophetic Imager

✓ Nahum's Description of Wrath: "The mountains quake before him; the hills melt; the earth heaves before him... His wrath is poured out like fire, and the rocks are broken into pieces by him." — Nahum 1:5-6

✓ Apocalyptic Visions: In the Book of Revelation, cataclysmic events use imagery resembling falling volcanic masses or burning peaks thrown into the sea (Revelation 8:8), though commentators debate whether these represent literal volcanic phenomenon, meteorites, or symbolic divine judgment.
