NOTICIA DE LA SETMANA 1: "Subtle helium emanations as predictive signal of imminent earthquake".

-Summary

Japanese researchers have found that, as some have suspected, there is a relationship between helium levels in groundwater and the amount of stress exerted on Earth's inner rock layers. This has been seen in localities near the epicenter of the Kumamoto earthquake of 2016. Scientists hope the finding will lead to the development of a surveillance system capable of detecting changes in tension that could portend a major earthquake.

Several studies, including some on the great Kobe earthquake in Japan in 1995, have indicated that changes in the chemical composition of groundwater may occur before seismic movements. However, researchers still needed to accumulate evidence to link with sufficient certainty the occurrence of earthquakes with such chemical changes.

A team of researchers from the University of Tokyo in Japan and their collaborators found that when the stress exerted on the earth's crust was high, so were the levels of an isotope of helium, helium-4, released into groundwater Near the epicenter of the 7.3-magnitude Kumamoto earthquake in southwestern Japan, which caused 50 deaths and serious material damage.

-Commentary

I think that this will be very usefull to detect the possible earthquakes in the future.

Several studies, including some on the great Kobe earthquake in Japan in 1995, have indicated that changes in the chemical composition of groundwater may occur before seismic movements. However, researchers still needed to accumulate evidence to link with sufficient certainty the occurrence of earthquakes with such chemical changes.
