Houthis attack tanker Andromeda Star in Red Sea
On April 27, 2024, Yemen's Houthi rebels launched a ballistic missile attack on the Panama-flagged oil tanker Andromeda Star in the Red Sea, causing damage to the vessel. The incident occurred amid ongoing Houthi attacks on commercial shipping in the region and heightened geopolitical tensions affecting maritime trade routes.
Peak 82.2 on Monday 29 April 2024. The shaded band is the incident window.
Where the attention came from
Social-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 81% of all days since 2020, and the highest since Friday 19 April 2024.
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.
How it was framed the frame glossary →
Lead frame: geopolitical pawn. Trade press was 6% of in-scope coverage — the story had left the trade press and gone mainstream. (Historical coverage is scored on headlines only.)
Acting, or acted upon
In 71% of coverage shipping was the thing acted upon rather than the actor; 35% of it was strongly negative in tone.
