Topical Lexicon
Overview

Strong’s 4578 refers to the sudden, often violent quaking of the earth through which God repeatedly announces His presence, judgment, deliverance, and the climax of history. Fourteen occurrences span the Gospels, Acts, and Revelation, linking the term to Christ’s atoning work, the advance of the gospel, and the consummation of the age.

Occurrences in the New Testament

Matthew 8:24 – a seismic storm on the Sea of Galilee tests the disciples’ faith.
Matthew 24:7; Mark 13:8; Luke 21:11 – earthquakes listed among “birth pains” preceding the end.
Matthew 27:54 – the centurion and those with him fear greatly “when they saw the earthquake and all that had happened.”
Matthew 28:2 – a “great earthquake” accompanies the angel’s descent at the empty tomb.
Acts 16:26 – “Suddenly a great earthquake shook the foundations of the prison,” opening doors for the Philippian jailer’s conversion.
Revelation 6:12; 8:5; 11:13 (twice); 11:19; 16:18 (twice) – increasingly severe quakes punctuate the seals, trumpets, and bowls.

Historical and Geographical Background

Palestine and Asia Minor sit on active fault lines (the Dead Sea Transform, the Anatolian plate boundaries). First-century readers were aware of devastating quakes such as those that destroyed Laodicea in AD 60 and Pompeii in AD 62–63. Scripture harnesses this cultural memory: real seismic events form the backdrop for prophetic warnings and divine interventions.

Theological Themes

1. Divine Self-Revelation

Earthquakes mark theophanies (compare Exodus 19:18; 1 Kings 19:11–12). At Calvary the ground shakes, declaring that the Creator grieves yet reigns (Matthew 27:54). At the resurrection the quake signals heaven’s verdict that death is defeated (Matthew 28:2).

2. Judgment and Warning

“Nation will rise against nation… and there will be famines and earthquakes in various places” (Matthew 24:7). The quakes of Revelation intensify from a sixth-seal global convulsion (Revelation 6:12) to a bowl judgment “such as had never occurred since men were on the earth, so mighty was the earthquake” (Revelation 16:18). God’s warnings grow louder as human rebellion persists.

3. Salvation and Deliverance

Acts 16:26 shows a quake not of destruction but liberation: “At once all the doors flew open, and everyone’s chains were loosed”. Physical shaking highlights spiritual release, prefiguring the gospel’s power to free captives (Isaiah 61:1; Luke 4:18).

4. Cosmic Renewal

Hebrews 12:26–27 recalls God’s promise to “shake not only the earth but heaven as well” so that what cannot be shaken may remain. The final earthquake of Revelation 16:18–20 removes islands and mountains, preparing for the new heaven and new earth (Revelation 21:1).

Christological Connections

• At His death the earth quakes; at His resurrection it quakes again. Creation responds to the Redeemer’s humiliation and victory.
• Jesus’ Olivet discourse places earthquakes among preliminary signs, underscoring His sovereign knowledge of history and the certainty of His return.
• In Revelation the exalted Christ breaks the seals and sends the judgments that include the quakes, affirming His authority over both natural and supernatural realms.

Pastoral and Homiletical Applications

• Security in Christ – Though the ground may tremble, “God is our refuge and strength… though the earth is moved” (Psalm 46:1–2).
• Urgency of Repentance – Revelation 11:13 reports that survivors “gave glory to the God of heaven,” showing judgments are meant to prompt repentance before final wrath falls.
• Mission amid Upheaval – Like Paul and Silas, believers are called to worship, witness, and serve even when the foundations shake (Acts 16:25–34).
• Hope of Unshakable Kingdom – Preaching on these texts directs hearers to the “kingdom that cannot be shaken” (Hebrews 12:28).

Related Old Testament Background

Isaiah 13:13, Haggai 2:6–7, and Ezekiel 38:19 anticipate end-time quakes. Zechariah 14:4 pictures the Mount of Olives splitting when the Lord returns, providing a geographical bridge between Testaments and reinforcing prophetic continuity.

Summary

Throughout Scripture, earthquakes serve as divine megaphones: announcing God’s holiness, validating Christ’s redemptive work, liberating His people, and heralding the approaching Day of the Lord. They challenge the complacent, comfort the trusting, and direct all creation toward the unshakable reign of God through Jesus Christ.
