Revelation 16:18 And there were noises and thunderings and lightnings; and there was a great earthquake, such a mighty and great earthquake as had not occurred since men were on the earth.

An earthquake results from a sudden release of pressure between the tectonic plates of the earth’s crust.
Most of the time an earthquake is localized, that is, it happens around a single location.
The most powerful earthquake since record keeping was May 1960 in Chile. It was a 9.5.
Earthquakes take place all the time – no fewer than 50 in the past 24 hours.
Most are small, only slightly noticeable, and all are scattered around the globe.
What would happen if every tectonic plate shifted at the same time?
It would devastate the world.
Buildings would tumble and topple.
Roadways would split.
Dams will break.
Pipelines will break.
Highlines will come down.
Heaven help those living near a nuclear power plant.
Not will the mainland be utterly devastated but tsunami’s would result in a catastrophic washing away of islands – Revelation 16:20 Then every island fled away, and the mountains were not found.
It’s ahead and you don’t want to be around for it.
There is only one escape – how shall we escape if we neglect so great a salvation. Heb 2:3
The escape is salvation through Jesus Christ.
