In a groundbreaking study that combines satellite technology with volcanic monitoring, researchers have shed new light on the eruptive activity of Volcán de Fuego in Guatemala. This stratovolcano, known for being one of the most active in the world, has been closely observed using the Normalized Hotspot Indices (NHI) algorithm, which operates on the Google Earth Engine (GEE) platform. The findings, published in the ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, highlight the potential for this innovative monitoring tool to enhance safety and preparedness in the construction sector, particularly in regions prone to volcanic activity.
Lead author N. Genzano from the Politecnico Milano emphasizes the significance of this research: “By analyzing 40 years of Landsat observations, we can accurately map periods of thermal activity and identify potential hazards associated with volcanic eruptions.” The study reveals that during major thermal events, such as those occurring between 2000-2003 and 2015-2018, extensive lava flows were recorded and mapped effectively through satellite imagery. This capability not only aids scientists in understanding volcanic behavior but also serves as a critical resource for construction professionals operating in the vicinity of active volcanoes.
The implications for the construction industry are profound. In regions where volcanic eruptions can disrupt infrastructure development, having access to real-time data on thermal activity can inform project planning and risk management strategies. Genzano notes, “The NHI algorithm allows us to characterize different eruptive phases and monitor changes in thermal activity, which could precede more dangerous eruptions.” This proactive approach to monitoring can help construction companies mitigate risks and protect their investments by adjusting timelines and project scopes based on the latest volcanic data.
Furthermore, the ability to predict volcanic activity with greater accuracy can lead to improved safety regulations and guidelines for construction practices in vulnerable areas. As cities expand into regions near active volcanoes, the integration of sophisticated monitoring tools like NHI into urban planning becomes increasingly vital. It underscores a shift towards data-driven decision-making in the construction sector, where safety and sustainability are paramount.
As this research demonstrates, the intersection of technology and environmental science is paving the way for more resilient construction practices. With tools like the NHI algorithm, professionals can not only respond to immediate threats but also prepare for long-term challenges posed by natural phenomena. The findings from Genzano and his team serve as a reminder of the importance of harnessing advanced technology to safeguard both lives and investments in an ever-changing world.
