The research drone in action on the island of Vulcano at the southern boundary of the Aeolian Islands - Composition of gases emitted by volcanoes can provide information on the possibility of imminent eruptions / Lightweight drones make investigation possible even in areas that are difficult to access The main gases released by volcanoes are water vapor, carbon dioxide, and sulfur dioxide. Analyzing these gases is one of the best ways of obtaining information on volcanic systems and the magmatic processes that are underway. The ratio of carbon dioxide levels to those of sulfur dioxide can even reveal the likelihood of an impending eruption. Drones are employed to carry the necessary analytical systems to the site of activity. However, because of their size, transporting the drones to their operation sites has to date required significant expense. A team headed by Professor Thorsten Hoffmann at Johannes Gutenberg University Mainz (JGU) has recently been assessing the potential for using a small, portable observation drone in remote regions. This very compact drone system can even be conveyed on foot to sites that are extremely difficult to access.
