A group of researchers from the University of Malaga of the Department of Applied Physics I they moved to the island of La Palma to implement an unprecedented technique, through a portable instrument, known as the plasma laser, which measures lava composition in real time and at a safe distance. What’s more, predicts the behavior of the volcanic eruption, and helps scientists study the evolution of the volcano.
The volcanic emergency suffered by the island of La Palma has caused the making of this instrument in three weeks, which is a record time, since this tool takes about three years to develop, as indicated by the Department of Applied Physics 1 of the University of Malaga.
How does this instrument work?
Santiago Palanco, teacher and ideologist of this instrument, launched this technique for measuring the lava component, through laser-induced plasma spectrometry at a distance of about 70 meters, to avoid the risk of burns when taking samples by hand.
The technique focuses on the Focusing the lava sample at a very high temperature through this tool, and those measurements are in charge of analyzing and recording them Spanish Geological and Mining Institute, and later they are contrasted with their own evaluations to determine the extent of the volcanic eruption.
Thus, The use of highly protective suits with a helmet, goggles and gas masks is mandatory, accompanied by some sensors provided by the Military Emergency Unit that warn of any harmful emissions to avoid greater risks in the measurement task. In the same way, recognizes that the affected area has a high risk of particles and gases, which can make the sampling task impossible with this tool and the withdrawal of troops.
