Muography for Inspection of Civil Structures

Instruments, 2022
Aging infrastructure is a threatening issue throughout the world. Long exposure to oxygen and moisture causes premature corrosion of reinforced concrete structures leading to the collapse of the structures. As a consequence, real-time monitoring of civil

Branched Conduit Structure Beneath the Active Craters of Sakurajima Volcano Inferred From Muography

Journal of Geophysical Research: Solid Earth, Volume 129, Issue 9, September 2024.
Abstract Observing in‐conduit physical mechanism underlying the switching of eruptive activity between the craters of multi‐vent volcanoes could contribute to hazard assessment at these complex volcanic edifices. We performed monitoring of mass density changes beneath two active craters of Sakurajima volcano in Kyushu, Japan between September 2018 and ...

Expanding the Spatial Reach and Human Impacts of Critical Zone Science

Earth's Future, Volume 12, Issue 3, March 2024.
Abstract Two major barriers hinder the holistic understanding of subsurface critical zone (CZ) evolution and its impacts: (a) an inability to measure, define, and share information and (b) a societal structure that inhibits inclusivity and creativity. In contrast to the aboveground portion of the CZ, which is visible and measurable, the bottom boundary

Muography as a new tool to study the historic earthquakes recorded in ancient burial mounds [PDF]

Geoscientific Instrumentation, Methods and Data Systems, 2020
Bidirectional muographic measurements were conducted at the Imashirozuka burial mound, Japan. The mound was built in the beginning of the 6th century as a megalithic tomb and later collapsed after a landslide caused by the 1596 Fushimi earthquake, one of

Simulation Study of 3D Imaging Method for Low and Medium Atomic Number Objects at Small Scale by Cosmic-ray Muon

Yuanzineng kexue jishu, 2022
Cosmic-ray muon imaging is a new non-destructive technique that uses highly penetrating natural muon to reconstruct objects with high atomic number (Z) or subjects hidden in something by applying muon scattering or transmission technique, respectively ...

Characterization and Performance Assessment of a SiPM-Based Muon Detector

Instruments
We present the upgrade and performance evaluation of a silicon photomultiplier (SiPM)-based muon detector, originally designed and developed 15 years ago for radiation tracking applications in radiographic imaging with cosmic muons.

Nuclear emulsion techniques for muography

Annals of Geophysics, 2017
Nuclear emulsions are currently being used in the field of muography, more specifically muon radiography of volcanic edifices and fault regions. The peculiar features of such detector for cosmic muons demand appropriate data processing and analysis techniques.

Background suppression for volcano muography with machine learning

Machine Learning: Science and Technology
A machine learning (ML) algorithm (deep neural network) is presented to suppress background in muography applications mainly targeting volcanoes. Additionally it could be applied for large scale geological structures, such as ophiolites.
