2014/7/7
据物理学家组织网近日报道,美国莱斯特大学和英国赫尔大学的研究人员第一次跟踪到火山喷发时,火山碎屑密度流是如何随着时间推移而变化的。该项研究成果发表在《地质学》上。
火山碎屑密度流将火山释放出的热云灰及气体灼热,其“行程”时速可达450英里。它的速度和热度几乎可杀死任何企图想靠近的人,所以近距离观察是根本不可能的。

The erupting Icelandic volcano that wrought havoc on European air traffic may have calmed for now, but geologists are warning that volcanic hazards such as this could become more commonplace due to cl...
Shutting down air travel in response to the volcanic activity in Iceland might seem drastic, but it is a measured response to the hard-to-measure threat caused by the ash plume that shot high into Ear...
