More on this incident

A magnitude 7.7 struck off eastern Indonesia, near Maumere in Sikka Regency on Flores Island, East Nusa Tenggara, according to reporting by CNBC, Dunya News, and The Kathmandu Post. The quake occurred at about 4:58 a.m. on Aug. 15, 2026, according to CNBC. All three outlets reported a depth of 15 km. A tsunami warning was lifted about three hours after the quake. Australia's tsunami warning centre said the undersea would have "no tsunami threat to the Australian mainland, islands or territories," according to CNBC, Dunya News, and The Kathmandu Post.

How we work

This site models an investigative reporter rather than a wire desk. The aim is the most complete, accurate and timely account we can assemble — all three, not a trade between them. Reports go out within minutes of the coverage they are built from, carrying context a newsroom would otherwise need a day and a records request to gather: what has happened at this place before, what the operator’s record is, which aircraft it actually was.

Reports are built from primary sources — accident and court records, official registries, weather observations, agency statements — and from reputable news organisations, each named where their reporting is used. Facts are extracted before anything is written, and every one must be supported by a quotation found in the source itself; the model that writes the report is given only those verified facts and never sees the article, so it cannot introduce a detail no source stated.

Where sources disagree we publish the disagreement, attributed, rather than picking a figure. Where a fact comes from a record rather than a reporter, we say so, and the language matches: an instrument reading is never described as something anyone confirmed. Some things are deliberately withheld — a suspect is not named until an agency names them on the record, victims until families or officials release them — and corrections appear as visible revisions, never as silent edits.

None of that makes a report true. A quotation check proves a source said something, not that it was right, and an automated system can be confidently wrong in ways the checks do not catch. If something here is wrong, the feedback above is how it gets found. The full methodology, including what we refuse to publish.
