UGA/CNRS press release

An international scientific team, including researchers from the Institut des Sciences de la Terre (ISTerre - CNRS/IRD/UGA/ Univ. Gustave Eiffel/USMB), has just discovered a reservoir of natural hydrogen in the depths of a chromite mine in Albania. This discovery, which opens up new prospects for the exploration of natural hydrogen, is the subject of an article published in Science magazine on February 8.
Natural, or geologic hydrogen (H2) has recently gained widespread interest due to (...)

New ambient background geophysical data provide an unprecedented 3D image of the deep geometry of the boundary between mantle and continental crust beneath the Western Alps, also known as the Moho. These high-resolution data enable the deep geometry to be correlated with sub-surface geological data.
These data show the presence of a cold, rigid mantle body located 20 kilometers below the Po plain south of Turin. This portion of the Adriatic mantle acts as an indentor, controlling the (...)

The western Alpine arc is characterized by moderate but constant seismic activity. Numerous studies (geodynamic and seismological, etc.) highlight the persistent scientific questions linked to Alpine dynamic processes and the associated rate of deformation (resulting from late continental collision phases), and to the assessment of seismic hazard and associated risks. Seismic monitoring in the northern French Alps was launched in 1987 with the installation of the first Sismalp seismological (...)

Simulation is an essential tool for improving people’s preparedness for disasters such as earthquakes, whose sudden and violent nature requires an effective emergency response. It can even be used by public authorities and crisis managers to implement the actions required to protect populations. With this in mind, a multi-disciplinary team of researchers, including two scientists from the ISTerre laboratory, has created an original computer model for the city of Beirut in Lebanon, which is (...)

When the Earth was completing its formation approximately 4.5 billion years ago, it was enveloped in a global ocean of molten magma, extending hundreds to thousands of kilometers beneath its surface due to violent impacts. This early environment bore little resemblance to the habitable conditions we experience on Earth today. Nonetheless, these initial few hundred million years were crucial in shaping our planet’s fundamental chemical and physical structures as we know them today. Key (...)
