Composite accident sequence timeline with Skala/DREG signals

(back)

Nikolai Karpan's book (often cited here) contains some of the most detailed timelines describing the chronology of the accident (as he sees it). His timelines are somewhat disorganized and disjointed into multiple sections of the book, so they have been translated and compiled below. In addition, the timelines from Annex I and II of INSAG-7 have been interspersed to create a composite timeline.

INSAG-7 events that wholly duplicate Karpan's entries have generally been omitted. Note the yellow shaded timestamps and comments, which indicate when events are repeated with different wording, or when the timing/details of an event are disputed/inconsistent.
