Houthis attack oil tankers in Red Sea
Houthi rebels attacked oil tankers in the Red Sea in late January 2024, including strikes on British and Russian vessels. The attacks prompted widespread tanker diversions from the Suez Canal, causing freight rates to surge and disrupting global oil shipping routes.
Peak 136.7 on Saturday 27 January 2024. The shaded band is the incident window.
Where the attention came from
Over the whole window this ran Mixed-led; on the peak day itself it read Social-led. When the two differ, the fast signals (social, news) spiked and faded while the slow ones (search, research) carried the tail. 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 94% of all days since 2020, and the highest since Sunday 31 December 2023.
How far it spread
Spilled over — 2 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.

Acting, or acted upon
In 84% of coverage shipping was the thing acted upon rather than the actor; 59% of it was strongly negative in tone.

- tier C: only a Wikipedia article, GDELT sub-vocabulary term, or social per-term query fired — not yet confirmed as a real maritime incident (Phase C naming/is_maritime_incident does that).
