Cargo ship attacked off Yemen coast
A cargo ship was attacked off the Yemen coast in early December 2020. UK Maritime Trade Operations confirmed awareness of the incident on December 5, though circumstances remained unclear. The attack occurred amid ongoing regional maritime security concerns.
Peak 55.8 on Wednesday 9 December 2020. 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 Media-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 47% of all days since 2020, and the highest since Saturday 26 September 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.
