Argentine port strike delays grain ships
More than 100 grain cargo ships were delayed at Argentine ports due to a strike by port workers in late December 2020. The incident disrupted cargo operations and highlighted supply chain vulnerabilities during the holiday season.
Peak 46.1 on Wednesday 23 December 2020. The shaded band is the incident window.
Where the attention came from
Public curiosity-led, both over the window and on the peak day. Social here is X alone — Bluesky only joins the series from July 2024 — so its level isn't directly comparable with today's series, though its share of this incident is real.
Bar = share of the extra attention over the whole window; the tick marks the share on the peak day alone, where the two differ.
How unusual it was
This was above 9% of all days since 2020, and the highest since Wednesday 23 December 2020.
How far it spread
No vessel type moved — 0 of 6 vessel-type groups drew clearly more readers than usual.
Bars start at 1× — normal readership for that vessel type, the weeks before the incident. Grey = no clear lift. "Over time" shows each group's daily readers through the window; "All 12 articles" breaks the six groups back into their members.
