美国地质调查局揭示夏威夷基拉韦厄火山熔岩喷泉机制

美国地质调查局的研究人员通过对基拉韦厄火山近期喷发活动的详尽观测，在《科学》杂志最新一期上发表了关于火山熔岩喷泉形成机制的研究成果。1研究团队在火山上部署了35个多功能监测站，配备地震仪、次声传感器、大地测量仪、气体传感器和热成像摄像机等多种设备，对这些能喷射数百米高的熔岩喷泉进行了迄今最详尽的记录和分析。1

基拉韦厄火山自1823年以来仅发生过三次熔岩喷泉活动。1这类现象在埃特纳火山、冰岛等其他火山地区也曾出现，喷射高度可达数百米。1

U.S. Geological Survey scientists have published new findings on the mechanisms driving lava fountains at Kilauea volcano in Hawaii, based on the volcano's recent eruptive activity 1. The research, appearing in a recent edition of Science magazine, represents the most detailed observation and recording to date of these spectacular fountains, which can shoot lava hundreds of meters into the air 1.

The study relied on an extensive monitoring network of 35 independent data collection stations positioned across the volcano 1. These stations were equipped with multiple sensor types, including seismometers, infrasound sensors, geodetic instruments, gas sensors, and thermal imaging cameras, enabling researchers to capture comprehensive data on the fountain phenomena 1. Kilauea has experienced only three lava fountain events since 1823, making this recent occurrence a significant opportunity for scientific investigation 1.
