Narrative

As-of analysis

Carried forward
Situation at a glance

Anak Krakatau erupted with a 14-kilometer plume on September 4. On September 5, an eruption prompted a three-kilometer exclusion zone, as “Anak Krakatau erupts in Lampung, residents warned to stay 3 km away” reported. [citation] Indonesian authorities suspended 209 flights at Jakarta’s Soekarno-Hatta airport on September 6, and Garuda Indonesia diverted two flights; “Jakarta airport suspends flights due to volcano ash” covered the disruption. [citation] On September 8, Dudy Purwagandhi reopened Soekarno-Hatta, while “Erupsi Gunung Anak Krakatau, 2.961 Penerbangan Terdampak hingga 7 September” reported flight impacts through September 7. [citation] “Five journalists lose contact near Anak Krakatau” reported the loss of contact on September 9; Indonesia SAR expanded its search on September 13, and Polresta Tangerang searched for five journalists and three crew members on September 15. [citation] Basarnas’s September 17 Event describes it ending a search for eight missing people, and “Indonesia ends search for eight people missing at sea” reported the announcement on September 18. [citation]

Assessment

The cited Events and headlines describe volcanic activity updates and search operations for people reported missing near Anak Krakatau. They do not establish that the eruption caused the loss of contact. The search accounts refer at different points to five journalists, five journalists and three crew members, and eight missing people; those differing descriptions do not establish a reconciled roster or final outcome. Indonesia’s September 8 report that an eruption phase had ended, its September 10 report of renewed eruption, and the September 13 account of easing activity are distinct updates, not a single settled description. The warning-system story reports an alert failure and its linked Event describes a software gap, but neither establishes that the gap caused the failure. The Virgo Transport 8 identification report does not establish that the vessel or victims belong to the Sunda Strait case.

A retained time step

This edition freezes the complete served membership and analysis available through its UTC cutoff. Later repairs or identity changes do not rewrite what this edition showed.

Stories, Events, and cast

Stories are reporting clusters. Events are coded occurrences within that reporting. The cast contains 240 canonical people and organizations linked to the retained evidence.

Typed connections

Story-to-Event edges identify supporting reporting. Entity-to-Event edges identify recorded actor or target participation. Mentions and analytical roles stay visibly distinct from recorded participation.

Core, precursor, and continuation labels organize the reading. They do not by themselves establish causation. Collapsed graph groups and paginated evidence change presentation only; counts use the complete retained edition.
