Monde · Indonesia53 morts après un séisme peu profond de magnitude 7.7 au large de Flores, à l’aubeRédigé 7 septembre 2026 à 21:22 UTCRegarderTranscription0:00A shallow magnitude [music] 7.70:02earthquake struck near Indonesia around0:045:00 a.m. local time on August 15th at0:06about 6 mi [music] depth, delivering0:08extreme shaking to an estimated 200,0000:11people and causing significant [music]0:12shaking damage near population centers0:14without generating a significant0:16tsunami. The quake [music] measured 7.7,0:18just 6 mi deep. That shallow depth is0:21why shaking was so intense where people0:22live,0:23>> [music]0:23>> and an estimated 200,000 people felt0:25that extreme shaking near the epicenter0:27region.0:28>> [music]0:28>> Significant shaking damage has been0:30reported near population centers, and0:31assessment of structural damage is still0:33underway, [music]0:34but no significant tsunami was0:36generated. That outcome spared distant0:38Indian Ocean coasts, including India and0:40Australia, that have been devastated by0:43Indonesia-source waves before. The depth0:45explains the contrast. At 6 mi, the0:48energy was close to the surface, so0:50communities felt severe shaking. But a0:52major tsunami requires a large vertical0:54push of the ocean floor to displace the0:56sea, and that did not happen in this0:58event despite its size. That assessment1:01is focused close to where people live,1:03where the early morning shock hit1:04hardest while many were still at home.1:06The absence of a major wave mattered far1:09beyond the epicenter region, with relief1:11along distant coasts across the Indian1:13Ocean that remain exposed to tsunamis1:15originating near Indonesia. The shock is1:17being set against how often large1:19earthquakes occur globally, and against1:21recent large shocks, including a1:22magnitude 8.0 near Venezuela and a large1:25quake near Colombia that preceded this1:27event. It is also being measured against1:29Indonesia's own magnitude 9.1 earthquake1:32and tsunami in 2004, which generated a1:34catastrophic wave, a comparison that1:36underscores why the absence of a1:38significant tsunami this time is1:39consequential.1:41What remains unresolved is the human1:43toll and the full scope. No confirmed1:45casualties, injuries, or detailed1:47infrastructure damage totals have been1:49released.1:50>> [music]1:50>> No precise epicenter impacts or list of1:52most affected islands and towns have1:54been provided.
