MV X-Press Pearl sinks off Sri Lanka
Container ship MV X-Press Pearl caught fire in late May 2021 and subsequently sank off the coast of Sri Lanka in early June, triggering environmental concerns over potential oil and chemical spills. The vessel was carrying nitric acid, plastics, and other cargo. Sri Lanka authorities prepared for a possible oil spill disaster and sought compensation from the ship's operator.
Peak 79.1 on Saturday 5 June 2021. 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 79% of all days since 2020, and the highest since Saturday 5 June 2021.
How far it spread
Stayed in one vessel type — 1 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.
