An Overview of the Mafic and Felsic Monogenetic Neogene to Quaternary Volcanism in the Central Andes, northern Chile (18-28°Lat.S)

Monogenetic volcanism produces small eruptive volumes with short eruption history, different chemical compositions, and relatively simple conduit. The Central Volcanic Zone of the Andes is internationally known as a natural laboratory to study volcanism, where mafic and felsic products are present. In this contribution, the spectrum of architectures, range of eruptive styles, lithological features, and different magmatic processes of the mafic and felsic monogenetic Neogene to Quaternary volcanoes from the Central Volcanic Zone of the Andes in northern Chile (18°S-28°S) are described. The major volcanic activity occurred during the Pleistocene, where the most abundant activity corresponds to effusive and Strombolian eruptions. This volcanism is characterized by external (e.g., magma reservoirs or groundwater availability) and internal (e.g., magma ascent rate or interaction en-route to the surface) conditions, which determine the changes in eruptive style, lithofacies, and magmatic processes involved in the formation of monogenetic volcanoes.

Holovulcano: Augmented Reality simulation of volcanic eruptions

"This paper describes an interactive holographic simulation of volcanic eruption. The aim of the project is to use Augmented Reality (AR) technology to visualize different volcanic eruptions for public education, emergency training, and preparedness planning purposes. To achieve this goal, a 3D model of the entire Vulcano Island in Italy has been created using real elevation data. Unity game engine and Microsoft Visual Studio have been used to develop HoloVulcano augmented/virtual reality simulation application. The current version of HoloVulcano simulates normal and unrest situations, single and long lasting Vulcanian, Plinian, and Strombolian eruptions. HoloVulcano has been developed for Microsoft HoloLens AR device. Wearing the HoloLens, users can interact with the volcano through voice, gazing, and gestures and view different eruptions from different points in the island. HoloVulcano will be used for training emergency exercises and public education."
