中智联合考察队将深入太平洋阿塔卡马海沟的未知深处。从瓦尔帕莱索港出发，搭乘中国科考船“探索一号”进行的为期三个月的任务旨在发现新物种并洞察地震和海啸。该合作让智利科学家使用其他国家没有的先进工具。
周一，中国科考船“探索一号”从智利港口城市瓦尔帕莱索出发，搭载研究人员展开为期三个月的考察，覆盖阿塔卡马海沟周边700公里（435英里）。阿塔卡马海沟是东太平洋最深且最少探索的区域之一。该考察历时三年筹备，由中国科学院深海科学与工程研究所和智利康塞普西翁大学千禧年海洋研究所领导。
考察委员会称，此次行动是该地区迄今规模最大的此类行动。智利大学1月9日声明指出：“多年来形成的联盟让智利科学家使用目前其他国家没有的工具，在一次任务中加速数年研究。”
任务包括33个研究站和近20次潜水器下潜，探测海沟深处。该任务对理解太平洋地震带沿线的俯冲过程至关重要，对中国、日本、朝鲜半岛和东南亚有直接影响。

President José Antonio Kast oversaw the start of Escudo Fronterizo plan works on Monday at Chacalluta border complex in Arica, featuring trenches up to three meters deep to curb irregular migration. The initiative divides Chilean opposition and prompts reactions from Peru and Bolivia. Ministers outlined 500 km coverage along the northern border.
Peru has begun excavation works on its side of the border with Chile, near the Santa Rosa complex in Tacna. Regional authorities insist it is a project to organize heavy truck traffic. This comes amid Chile's border hardening measures.

Scientists have used swarms of minuscule earthquakes to map a hidden and intricate tectonic structure beneath northern California. This region, at the intersection of the San Andreas fault and the Cascadia subduction zone, involves five moving pieces rather than the expected three. The findings help explain past seismic events and improve hazard predictions.
Researchers at Stanford University have developed the first worldwide map of rare earthquakes occurring deep in Earth's mantle, rather than the crust. These elusive events cluster in regions like the Himalayas and near the Bering Strait. The study, published on February 5 in Science, identifies hundreds of such quakes and introduces a new method to detect them using seismic waves.

An international team of scientists has documented nearly 800 species, many previously unknown, living nearly 4,000 meters below the Pacific Ocean's surface. Their five-year study in the Clarion-Clipperton Zone also tested the environmental impacts of deep-sea mining, finding significant local reductions in animal numbers and diversity. The findings, published in Nature Ecology and Evolution, provide crucial data for regulating future extraction of critical metals.
Chile holds nearly 40% of the world's astronomical observation capacity, which could exceed 60% early next decade with telescopes like the Giant Magellan Telescope. Óscar Contreras-Villarroel, vice president and Chile representative for the project, stresses protecting dark skies and installation sites through consistent regulations.
