4^th Trumpet: And the fourth angel sounded the blast of a trumpet; and the third part of the light, as the eastern sun, was inflicted and smitten in a calamity; and the third part of the moon, and the third part of the stars, as stretching across the sky; so as a result, the third part of them was darkened and obscure; and the day did not shine for a third part of it, and the night likewise in a similar manner. [Revelation 8:12].

04.  This is a dramatic increase of volcanic eruptions, producing towering ash clouds, surrounding one third of the earths’ surface. The Saved are still on the earth.

4^th Vial:  And the fourth angel poured out his broad shallow cup and vial upon the light, of the rising sun in the east; and power was given unto him to scorch human beings with fire. And human beings were burned and scorched with a great and mighty burning, glowing heat; and they began to blaspheme and speak evil and defame, the name of the very exceeding great God; who has the authority, mastery and power over this stroke of a calamity and these plagues: and they did not repent or think differently or reconsider to give Him glory, honor and worshipful praise. [Rev. 16:8-9].

Phase Four:  6th Seal, 4th Trumpet, 4th Vial

[Rev. 6:14] And the heaven departed as a scroll when it is rolled together; and every mountain and island were moved out of their places.

[Rev. 8:12] And the fourth angel sounded, and the third part of the sun was smitten, and the third part of the moon, and the third part of the stars; so as the third part of them was darkened, and the day shone not for a third part of it, and the night likewise.

[Rev. 16:8-9] And the fourth angel poured out his vial upon the sun; and power was given unto him to scorch men with fire. And men were scorched with great heat, and blasphemed the name of God, which hath power over these plagues: and they repented not to give him glory.

This is a two-roll Jewish scroll that rolls together toward the center. As one looks upon an open scroll, much writing is in full view of the reader’s eyes. However, as one slowly rolls the two ends toward each other, the writing slowly but surely disappears from view bit by bit--- and finally disappears completely when the two rolls meet. When numerous volcanoes begin to erupt at the first trumpet, the upper stratosphere will not immediately be filled with ash. It will take time but gradually the suspended volcanic cloud bands of ash will roll themselves together --- and one by one all the heavenly bodies will fade from view. The spread of volcanic clouds in the stratosphere will occur in stages. When the fourth trumpet sounds, the distribution of suspended ash will be such that at any given location the heavenly bodies will only be visible about one-third of a twenty-four-hour period. The complete filling of the earth’s atmosphere does not occur until shortly after the fifth trumpet. By the last drop of the fourth vial, the injection of volcanic hydrogen chloride by violent upward projection will have virtually destroyed the ozone layer. Without this protective ozone shield, ultraviolet radiation will pour down upon those left behind after the Rapture. The beginning of skin cancer at the first vial will have reached plague proportions by the fourth vial. Ultraviolet radiation is a scorching fire as compared to the radiation we now receive from the sun at the earth’s surface.

The thickness of the ozone layer—that is, the total amount of ozone in a column overhead—varies by a large factor worldwide, being in general smaller near the equator and larger towards the poles. It also varies with season, being in general thicker during the spring and thinner during the autumn in the northern hemisphere. The reasons for this latitude and seasonal dependence are complicated, involving atmospheric circulation patterns as well as solar intensity.

Since stratospheric ozone is produced by solar UV radiation, one might expect to find the highest ozone levels over the tropics and the lowest over polar regions. The same argument would lead one to expect the highest ozone levels in the summer and the lowest in the winter. The observed behavior is very different: most of the ozone is found in the mid-to-high latitudes of the northern and southern hemispheres, and the highest levels are found in the spring, not summer, and the lowest in the autumn, not winter in the northern hemisphere. During winter, the ozone layer actually increases in depth. This puzzle is explained by the prevailing stratospheric wind patterns, known as the Brewer-Dobson circulation. While most of the ozone is indeed created over the tropics, the stratospheric circulation then transports it poleward and downward to the lower stratosphere of the high latitudes. However in the southern hemisphere, owing to the ozone hole phenomenon, the lowest amounts of column ozone found anywhere in the world are over the Antarctic in the southern spring period of September and October.

The ozone layer is higher in altitude in the tropics, and lower in altitude in the extratropics, especially in the polar regions. This altitude variation of ozone results from the slow circulation that lifts the ozone-poor air out of the troposphere into the stratosphere. As this air slowly rises in the tropics, ozone is produced by the overhead sun which photolyzes oxygen molecules. As this slow circulation bends towards the mid-latitudes, it carries the ozone-rich air from the tropical middle stratosphere to the mid-and-high latitudes lower stratosphere. The high ozone concentrations at high latitudes are due to the accumulation of ozone at lower altitudes.
