Drone attack on tanker in Arabian Sea
A tanker was attacked by drone in the Arabian Sea on July 30, 2021, killing two crew members. Israel and the US blamed Iran for the attack, which escalated Iran-Israel maritime tensions. Iran denied involvement. The incident also coincided with reports of a separate tanker seizure by Iran-backed forces and routine tanker market news.
Peak 76.1 on Tuesday 3 August 2021. 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 74% of all days since 2020, and the highest since Saturday 5 June 2021.
How far it spread
No vessel type moved — 0 of 6 vessel-type groups drew clearly more readers than usual.
Readers here means readers of the Wikipedia article on each vessel type — the same source as the Research signal, not news coverage — so an incident can dominate the news without moving this panel. 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 3% 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 69% of coverage shipping was the thing acted upon rather than the actor.
How the coverage sounded
Coverage ran 64% negative overall; 49% strongly so.
Each article is scored on a five-step scale from strongly negative to strongly positive; the bar is the share of coverage at each step.
