The Order of Revelation

In what order will the visitations in the book of Revelation unfold? Will the seals, trumpets, and bowls be rolled out back-to-back without overlap? Or will they overlap and stack up with increasing intensity, even as the waters of the flood deepened and intensified?

This question is not merely academic. How we understand the order of the visitations has significant impact on the interpretation several of them , as well as on our handling of the signs in the heavens which herald the day of the Lord and our understanding of when the two witnesses minister—the first half of the week or the second.
