宇宙射线 μ 子射线照相 (muography) 是一种成像技术，可以测量火山锥顶部几百米内的岩石密度，目前在最佳检测条件下已实现了 10 米量级的空间分辨率。 Muography 提供火山大厦顶部区域的图像，其分辨率比其他传统方法（即重力法）通常获得的分辨率要好得多。我们期望这种精确的测量能够为我们提供有关岩石密度分布异常的信息，这种分布可能受到密集的熔岩管道、低密度岩浆供应路径或上覆土壤深度压缩的影响。 VESuvius (MURAVES) 项目的 MUon 射线照相术目前正处于建设和部署的最后阶段。维苏威火山的斜坡上将安装多达四个μ子视距仪，每个μ子视距仪的表面约为1平方米，并采集至少12个月的数据。我们将使用测绘剖面，结合重力和地震测量活动的数据，确定维苏威火山口底部熔岩塞的地层，从而推断潜在的喷发路径。在 MURAVES 项目展开的同时，其他人正在斯特龙博利岛使用乳液探测器来研究火山顶部的熔岩通道。这些测量正在进行中：他们已经完成了两次测量活动，现在正在执行第一次数据分析。本文是 Theo Murphy 会议问题“宇宙射线 muography”的一部分。
Cosmic-ray muon radiography (muography), an imaging technique that can provide measurements of rock densities within the top few 100 m of a volcanic cone, has now achieved a spatial resolution of the order of 10 m in optimal detection conditions. Muography provides images of the top region of a volcano edifice with a resolution that is considerably better than that typically achieved with other conventional methods (i.e. gravimetric). We expect such precise measurements, to provide us with information on anomalies in the rock density distribution, which can be affected by dense lava conduits, low-density magma supply paths or the compression with the depth of the overlying soil. The MUon RAdiography of VESuvius (MURAVES) project is now in its final phase of construction and deployment. Up to four muon hodoscopes, each with a surface of roughly 1 m2, will be installed on the slope of Vesuvius and take data for at least 12 months. We will use the muographic profiles, combined with data from gravimetric and seismic measurement campaigns, to determine the stratigraphy of the lava plug at the bottom of the Vesuvius crater, in order to infer potential eruption pathways. While the MURAVES project unfolds, others are using emulsion detectors on Stromboli to study the lava conduits at the top of the volcano. These measurements are ongoing: they have completed two measurement campaigns and are now performing the first data analysis. This article is part of the Theo Murphy meeting issue ‘Cosmic-ray muography’.
