بلایای طبیعی · Southeastern Pacific quakeEaster Island earthquake: Magnitude 6.4 strikes far offshoreمکتوب ۷ آبان ۱۴۰۵ ساعت ۱۲:۰۷ (UTC)تماشامتن پیادهشده0:07A magnitude6 .4 earthquake struck far offshore from Easter Island.0:11Disaster monitors estimate low humanitarian impact.0:14With the epicenter far from island and mainland communities, the uncertainty is0:17whether the earthquake caused any effects along the nearest coasts.0:20The epicenter was one four hundred and eighty three kilometers southeast of0:24Hangaroa, Easter Island's main settlement.0:27It was also two one hundred and fifty four kilometers west of Libu on mainland Chile0:32and two one hundred and fifty seven kilometers west northwest of Anchud.0:36The earthquake occurred on October29,2026 , at7 :40 ,9 UTC,0:42less than four hours before this report.0:44Easter Island is also known as Rapanui.0:47Its name provides a geographic reference for an earthquake well out in the0:50southeastern Pacific.0:51Hangaro lies far from the earthquake center.0:53The distances to island and mainland settlements describe where the quake happened.0:57They don't tell us how many residents experienced shaking.1:00Seismologists have reviewed two solutions for the earthquake.1:03Both give magnitude6 .4.1:05The US Geological Survey uses a moment magnitude measure and places the origin ten1:10kilometers below the surface.1:11The depth estimates differ by seven kilometers.1:14The US agency gives ten kilometers, while the European Mediterranean Seismological1:18Center gives three.1:19Their origin times differ by one second, and their epicenter coordinates also differ1:23slightly.1:24Both describe a shallow earthquake in the same offshore region.1:27The European solution places the epicenter one, four hundred and eighty seven1:31kilometers east, southeast of Hangaro, and two, two hundred and three kilometers1:35west of Valdivia, Chile.1:37These are separate agency estimates for the same event.1:39Disaster monitors classify the earthquake's potential humanitarian impact as low.1:43Their assessment weighs the magnitude, the population potentially exposed, and1:47people's vulnerability.1:48It estimates possible consequences before a full picture of conditions on the ground1:52is available.1:53The shaking loss alert has a separate discrepancy.1:56Pager, the system used to estimate earthquake fatalities and economic losses,2:00appears differently across the event listings.2:03One listing carries no shaking.2:04Loss alert.2:05While another carries green, green indicates a low likelihood of fatalities and2:09economic losses.2:11It's unclear when any underlying alert changed.2:13A green estimate still leaves actual local conditions to be checked.2:16The other early indicators also need care.2:18The shaking model listed intensity one.2:21The public report count stood at zero nearly four hours after the earthquake.2:25Those indicators can't tell us whether anyone actually felt shaking.2:28Tsunami monitoring carries another important limit.2:31The earthquake listing has no tsunami flag, and disaster monitors display zero meter2:35values in two wave fields.2:37Both wave fields show zero meters, but they haven't been confirmed as tide gauge2:41measurements.2:42An event specific tsunami determination from the Pacific Tsunami Warning Center or2:46Chile's Naval Tsunami Authority hasn't been confirmed either.2:49The low impact estimate supports a limited expectation of harm, while coastal2:53effects still need confirmation.2:55No casualties, damage, or inundation have been confirmed.مقاله را بخوانیدخط زمانی داستانHeyDex
