Description and objectives

The MAGMA project aims to develop a compact, high-sensitivity sensor platform for real-time monitoring of sulphur dioxide (SO₂) and hydrogen sulphide (H₂S) in volcanic areas, using optical sensors based on quartz-enhanced photoacoustic spectroscopy (QEPAS). These gases are important indicators of volcanic activity, and their timely detection is essential for assessing environmental and health risks.

The proposed system uses advanced laser sources and miniaturised detection modules to ensure high selectivity, sub-ppmv sensitivity, resistance to interference and low maintenance. The project includes spectral study phases, design and construction of bench prototypes, assembly of the sensor box, calibration with certified mixtures, and outdoor testing in real environments.

The expected results include reliable data for volcanic risk management, an increase in TRL to pre-industrial levels, and technology that can be easily integrated into environmental monitoring networks. The initiative is part of the PNRR (National Recovery and Resilience Plan), promoting innovation, sustainability, and public health protection.
