Chernobyl disaster

The Wikipedia article on Chernobyl disaster has been edited 12,781 times since it was created in 2002, by 5,491 distinct accounts and IP addresses. That averages about 533 recorded changes a year, or several every day, which puts it among the more actively maintained pages on the encyclopedia.

Within the revisions retrieved for this report, the ten busiest contributors account for about 36% of the changes, with the rest spread across a long tail of occasional editors. That is a fairly typical mix of regular maintainers and passing corrections. In the same window, about 9% of the retrieved revisions came from bot accounts, which handle routine work such as link repair and reference formatting.

Within the retrieved window, 2026 carries the most recorded activity, with 226 changes. The page is currently busy: 85 of those revisions fall in the last 90 days. The most recent recorded edit was 21 days ago.

Readership has been broadly stable across the last two years of pageview data. The clearest peak in that record falls in April 2026. Traffic spikes and editing spikes often line up, but the revision record alone cannot tell you which one caused the other, or whether an outside event drove both.

This report is built from the 500 most recent revisions retrieved from Wikipedia, about 4% of the 12,781 recorded edits. Figures drawn from that window describe the window only, and the report cannot establish why a change was made or whether it was correct.
