金星未眠！至少37个火山结构最近仍活跃（图）
金星未眠 火山结构 活跃
2020/7/24
许多科学家一直认为，在过去5亿年里，金星缺乏板块运动，在地质上处于休眠状态。但美国和瑞士科学家在最新一期《自然·地球科学》杂志上撰文称，他们在金星上发现了37个近期可能活跃的火山结构，表明金星并非此前人们认为的“休眠世界”。许多科学家一直认为，在过去5亿年里，金星缺乏板块运动，在地质上处于休眠状态。但美国和瑞士科学家在最新一期《自然·地球科学》杂志上撰文称，他们在金星上发现了37个近期可能活跃的火...

极端降雨或可诱发火山喷发
极端降雨 可诱发 火山喷发
2020/4/23
美国科学家团队在一项最新地球科学研究中称，极端降雨会激活深层岩浆运动，而发生在2018年的基拉韦厄火山喷发，可能就是由极端降雨触发的。这一发现表明在评估火山灾害时，应将降雨纳入考量范围。相关研究报告22日发表于英国《自然》杂志。
