Monitoring degassing behaviour and eruption precursors at Ol Doinyo Lengai volcano, Tanzania

东非裂谷系统是地球上一些最独特和最危险的火山的所在地。其中之一是坦桑尼亚北方的伦盖火山，其特征是任何陆地火山中观察到的一些最显着的特征，能够产生剧烈的火山碎屑喷发。伦盖火山（Ol Doinyo Lengai）是世界上最持久的高二氧化碳脱气火山之一，但其偏远程度使科学家难以定期访问。该项目将研究新的远程气体和同位素传感技术，以量化Ol Doinyo Lengai火山的日常脱气行为。该项目的总体目标是促进国际社会努力建立一个地方性的长期监测伙伴关系。这有望提供比目前通过稀疏的短期实地活动获得的分辨率高得多的数据。在整个项目中使用的遥感和监测技术将包括使用定制的遥测气体传感模块，用于步行穿越、无人驾驶飞机飞行和永久性山顶站。这些数据将被汇编和呈现为火山的三维浓度分布模型。

The East African Rift System plays host to some of the Earth's most unique and hazardous volcanoes. Among them is Ol Doinyo Lengai volcano in northern Tanzania, characterised by some of the most remarkable features observed of any terrestrial volcano and capable of producing violent pyroclastic eruptions. Ol Doinyo Lengai is one of the most persistently high-CO2 degassing volcanoes worldwide, yet its remoteness has made it difficult for scientists to access regularly. This project will investigate novel remote gas and isotope sensing techniques to quantify the day-to-day degassing behaviour of Ol Doinyo Lengai volcano. The overarching goal of this project is to contribute towards international efforts to set up a local, long-term monitoring partnership. This promises to provide significantly higher resolution data than is currently being achieved through sparse, short-term field campaigns. Remote sensing and monitoring techniques used throughout this project will include the use of custom-built telemetric gas sensing modules, set up for walking traverses, drone flights and permanent summit stations. Data from these will be compiled and presented as a 3D concentration profile model of the volcano.
