This article describes an interactive holographic visualization of volcanic eruption application for Microsoft HoloLens device. The aim of the project is to use this technology to visualize different eruptive phenomena on an active volcano for public education, emergency training, preparedness planning purposes, and raising awareness among tourists. We have selected La Fossa volcano on Vulcano island (Italy) as a case study and, thus, the application is named HoloVulcano. Unity game engine and Microsoft Visual Studio were used to develop the HoloVulcano augmented/virtual reality visualization application. The current version of HoloVulcano visualizes volcanic phenomena typically associated with unrest (fumaroles) and explosive eruptions (e.g. eruptive plumes, ejection of ballistic blocks, bombs, and pyroclastic density currents). The eruption types are developed based on existing literature using Unity game engine's particle systems component. HoloVulcano is a Microsoft HoloLens device application. Wearing the HoloLens, users can interact with the application through voice, gazing, and gestures and view different volcanic phenomena from different sites and angles on the island. HoloVulcano can be used by emergency managers and teachers for training, emergency exercises, and public education.

使用 Microsoft Hololens 模拟和可视化火山现象：以 Vulcano 岛为例（意大利）

本文介绍了适用于 Microsoft HoloLens 设备的火山喷发应用程序的交互式全息可视化。该项目的目的是使用这项技术将活火山上的不同喷发现象可视化，以用于公共教育、应急培训、备灾规划和提高游客意识。我们选择了位于 Vulcano 岛（意大利）的 La Fossa 火山作为案例研究，因此，该应用程序被命名为 HoloVulcano。Unity 游戏引擎和 Microsoft Visual Studio 用于开发 HoloVulcano 增强/虚拟现实可视化应用程序。当前版本的 HoloVulcano 可视化了通常与动荡（喷气孔）和爆炸性喷发（例如喷发羽流、弹道块、炸弹和火山碎屑密度流）相关的火山现象。喷发类型是基于现有文献使用 Unity 游戏引擎的粒子系统组件开发的。HoloVulcano 是 Microsoft HoloLens 设备应用程序。佩戴HoloLens，用户可以通过语音、凝视和手势与应用程序进行交互，从岛上不同地点和角度查看不同的火山现象。HoloVulcano 可供应急管理人员和教师用于培训、应急演习和公共教育。
