Researchers unwind the secret of volcanic emissions

Russian and Italian researchers have recently come nearer to understanding volcanic emissions by studying Monte Nuovo close to Naples as a basis. Lava, the molten rock that forms and afterward sets on the Earth’s surface, contains data that can uncover the reasons for ejections, yet in addition unwind the riddles of the planet’s past and future.

The investigation of Italian volcanoes has propelled on account of the new physical techniques for Professor Sultan Dabagov’s laboratory at MEPhI and INFN (National Institute of Nuclear Physics in Italy). The most recent advances in physics were utilized in the exploration, which has enabled researchers to get the data “recorded” in the remaining parts of an emission.

“Our work is a detailed study of the active phase in the planet’s life, which manifests itself in the form of volcanic eruptions. Eruptions are complex phenomena, and finding the correlations between their many variables is a step toward understanding and prediction. We used powerful sources of X-ray radiation capable of penetrating deep into the studied samples without destroying them,” Sultan Dabagov, the research director, professor at the Institute of Nanotechnology in Electronics, Spintronics, and Photonics at MEPhI, told Sputnik.

As per the researcher, in the first stage, they studied volcanic samples utilizing multi-capillary optics dependent on X-rays. At that point, to affirm the outcomes, they examined the samples utilizing powerful synchrotron radiation. This made it conceivable to acquire X-rays and tomograms of the samples, reproduce the internal highlights of different rocks and get high-resolution three-dimensional models.

The specialists believe that breaking down these models in contrast with samples of different emissions will prompt conclusions about historically known ejections and the ejections of active and passive volcanoes.

“The data obtained using computed tomography and synchrotron radiation can be integrated into the general environment of feature-finding methods used in geology. We can better understand the impact of micro- and nanoporosity of the studied rocks on their permeability in order to answer many important questions on the formation and the future development of the planet,” Sultan Dabagov said.

The work of the Russian and Italian researchers is planned for making a tool that allows for detailed tomographic analysis in a lab utilizing a low-power X-ray tube. This is conceivable with multi-capillary optics.

The new tool will take into account the continuous study of volcanic samples since it is smaller and less expensive than synchrotron sources (this will help prepare almost any geographical research center). As indicated by specialists, the utilization of multi-capillary optics with small-sized sources and radiation detectors can form the reason for making reduced convenient gadgets for examining different rocks on the ground, without moving samples.
