HOME > Geological Survey of Japan
Geological information is essential for a country like Japan, located at a tectonically active area, to ensure a safe and secure society. The Geological Survey of Japan gathers, compiles, and provides geological information and promotes its wider use. We also develop technologies to overcome various difficulties related to global environment protection, exploration of minerals and energy resources, and natural disaster mitigation, and coordinate international cooperation as a national representative.
Researchers in AIST developed a measurement method of oleic acid in live cattle by magnetic resonance. A magnetic resonance experiment was conducted on beef fat samples, and it was found that the length of the proton transverse relaxation time is highly correlated with the content of unsaturated fatty acids such as oleic acid in beef fat. This was used to successfully estimate the oleic acid content with an error of 2.2 % from the proton transverse relaxation time of beef fat. The application of this discovery to analysis of data acquired by a magnetic resonance surface scanner in separate development will pave the way to enable nondestructive, noninvasive, in-situ measurement of unsaturated fatty acid content in live beef cattle.

AIST released a database of volcanic ash ejected from major eruptions in Japan and abroad. This is the world’s first database that records information such as microscopic images of volcanic ash particles, their eruption styles, and volcanic activity. The database covers most of the volcanic ash from major eruptions in Japan in the 21st century as well as older eruptions and samples collected from eruptions abroad. This database will enable to rapidly search and identify information on past volcanic ash with similar characteristics when a new eruption occurs, which will contribute to the mitigation of eruption disasters by immediately understanding the mechanism of the eruption and predicting its transition.

A database that includes microscopic images of volcanic ash and information of major eruptions in Japan and abroad has been created and is available online
