Počet obětí zemětřesení v Japonsku stoupl na nejméně třináct, záchranáři bojují s časem

Index ověření faktů: 58/100 — The death toll, magnitude revision, quake location/date, and survivor quotes are all directly supported by the two BBC sources, but the industrial/economic context, the G7 claim, and the callback to the earlier mall/explosion story are unsupported by the material provided.

• At least 13 people have died after the earthquake — Matches BBC video source: 'At least 13 people have been killed after the earthquake struck the island of Kyushu on Tuesday.'
• Earthquake struck Kyushu on Tuesday — Directly stated in BBC video source.
• Japanese authorities in a 'race against time' to rescue survivors — Matches BBC video headline verbatim.
• Quake magnitude now cited as 6.8, down from earlier 7.1 reading — BBC article source states '6.8-magnitude quake'; the 7.1 figure is attributed to the outlet's own earlier report, which is not in the provided source set but is plausible as self-referential context.
• Magnitude revisions are 'a common pattern' after major earthquakes — General editorializing/analysis not stated in either BBC source; presented as fact without citation.
• Survivor quote: 'I thought I would die' — Matches BBC article headline: "'I thought I would die': Survivors describe the shock and horror..."
• Survivors are still wrestling with shock as search continues — BBC article source: 'as survivors wrestle with the shock.'
• Rescue operations ongoing, crews searching for people trapped beneath collapsed structures — Both sources confirm ongoing rescue operations tied to trapped/killed victims.
• Japan is a G7 economy — True general fact but not stated in either provided source; added without citation.
• Kyushu hosts a dense cluster of electronics and semiconductor plants feeding global supply chains — Not mentioned in either BBC source; asserted as established fact without a citation despite being plausible real-world knowledge.
• No available reporting yet quantifies factory/production damage — Reasonable inference given the silence of the two cited sources on this topic, but not something the sources explicitly confirm as an open question.
• Earlier coverage described people trapped in a mall and confusion over a possible explosion — This refers to the outlet's own prior article, which is linked but not included in the supplied source material, so it cannot be checked against the given sources.
