监测处于动荡状态的火山爆发事件的频率、强度/规模和动态是调查和预测其活动的关键。对喷发现象的热视频和视频观测及其与形变和地震网络数据的相关性往往受到技术限制，包括缺乏时间同步、数据量和功耗。目前有几种解决方案，在这里，我们提出了一种仪器，设计用于在可见光和热红外波长的火山爆炸事件的永久和实时观测，其输出可以与辅助监测数据完全同步。我们的系统（维吉亚：视觉和红外地面图像分析仪）采用边缘计算方法，即在现场处理信息，定期向当地观测站发送报告，由该系统“决定”何时获取高时间分辨率数据，以捕捉关键的爆炸事件。作为一个永久性的装置，维吉亚能够对火山活动进行连续、长期和时间同步的观测，同时降低功耗和数据量。我们建议VIGIA风格的仪器可以提供有用的科学和监测信息，并在这里提供组件，组件和代码的关键细节，以便天文台可以复制系统，并以最低的成本建立自己的维吉亚。我们使用的Reventador火山，在厄瓜多尔，作为一个案例研究，以介绍该仪器的能力。
The monitoring of the frequency, intensity/magnitude and dynamics of explosive events at volcanoes in a state of unrest is key to surveying and forecasting their activity. Thermal and visual video observations of eruptive phenomena, and their correlation with data from deformation and seismic networks, are often limited by technical constraints including lack of time synchronisation, data volumes and power consumption. Several solutions are currently available and here we present an instrument designed for the permanent and real-time observation of volcanic explosive events in the visible and thermal infrared wavelengths, the output of which can be fully synchronised with ancillary monitoring data. Our system (VIGIA: visual and infrared ground-based imagery analyser) follows an edge computing approach whereby information is processed on-site, and periodic reports are sent to the local observatory and the system “decides” when to acquire high-temporal resolution data so as to capture key explosive events. As a permanent installation, VIGIA enables the continuous, long-term and time-synchronised observation of volcanic activity while reducing power consumption and data volumes. We suggest that VIGIA-style instruments could provide useful scientific and monitoring information, and provide here the key details of the components, assembly, and code so that observatories can replicate the system and build their own VIGIA at minimal cost. We use the Reventador volcano, in Ecuador, as a case study to present the capabilities of the instrument.
