Researchers from France have developed an interesting method for studying volcanoes. For this they used an idea they borrowed from… laboratory research rooms. Victory? Incredibly interesting.
Everyone can see what a volcano looks like… at least if one is nearby. In Poland we only have extinct volcanoes, but we usually look at them from below and from the outside. A French team of researchers from the French National Center for Scientific Research (CNRS) and the Paris Institute of Planetary Physics (IPGP) used a variety of observations from medical imaging and optical microscopes to look at such an object from the inside like never before before.
What do volcanoes hide?
This method uses a known, existing matrix imaging technique. It helps overcome some of the problems that have hindered volcano mapping in the past. This allowed us to look inside these objects and show the magma underneath. Usually, the problem was the lack of many sensors called geophones, which were used to record seismic waves bouncing through the Earth. Their interpretation has been a problem until now, but matrix images come to the rescue. This translates into more detailed information about the magma below the surface.
A French team has developed a new method of combining data from multiple geophones to discover details that individual geophones could not capture on their own. According to sciencealert.com, Part of the success of this method is the reduction of distortions that occur when seismic waves reflect different features in the ground.. In the studied case of La Soufrière volcano in Guadeloupe, it was possible to reveal the structure of this object which was hidden up to 10 kilometers below the surface.
The whole picture certainly helps in understanding what is going on below the surface, and not just for this particular volcano. Such information will also help to more accurately predict possible eruptions in other places around the world. This could help save many lives, but it also helps to plan better actions related to the explosion itself and its effects. This is, for example, the question of managing flights in the area, which could be canceled under the so-called red code.
