Pirates attack tanker Stolt Apal off Yemen
A UK-flagged tanker, the Stolt Apal, was attacked by pirates off the coast of Yemen in the Gulf of Aden on May 17, 2020. The ship's crew repulsed the attack. The incident generated significant maritime news coverage during the detection window.
Peak 53.5 on Thursday 21 May 2020. The shaded band is the incident window.
Where the attention came from
Mixed-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 40% of all days since 2020, and the highest since Thursday 14 May 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.
How it was framed the frame glossary →
Lead frame: human drama. Trade press was 0% 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 61% of coverage shipping was the thing acted upon rather than the actor; 6% of it was strongly negative in tone.
