Scientists have developed a method to rapidly obtain valuable information about the risk of a volcano erupting by analyzing three key parameters: the height of the volcano, the thickness of the rock layer separating the volcano’s reservoir from the surface, and the average chemical composition of the magma. This method opens new prospects for identifying and monitoring active volcanoes that present the greatest risk, without the need for major technical and financial resources.
What is the risk of a volcano erupting? To assess the likelihood of a volcanic eruption, researchers require insights into the volcano’s internal architecture. However, acquiring this essential data can be a long-term undertaking, involving years of field studies, analyses, and continuous monitoring. This is why only a fraction—approximately 30%—of active volcanoes are currently well documented.has developed a method for rapidly obtaining valuable information.

Credit: Oliver Higgins This method uses three easy-to-measure parameters: the height of the volcano, the thickness of the rocks separating the volcano’s “reservoir” from the surface, and the chemical composition of the magma released over its eruptive history. The first can be determined by satellite, the second by geophysics and/or chemical analysis of minerals in the volcanic rocks, and the third by direct sampling in the field.
