NEWTON-g aims at developing a field-compatible gravity imager to constrain movements of subsurface fluids through collecting continuous images of the gravity field. This system will include an array of low-costs MEMS-based relative gravimeters anchored on an absolute quantum gravimeter. The adjustable positions of the gravimeters and the continuous logging of gravity data will shed light on the variations of subsurface fluid properties with unprecedented spatial and temporal resolutions. The new gravity imager will be tested at Etna volcano (Italy), as it is an excellent natural laboratory due to frequent gravity fluctuations and the presence of a multi-parameter monitoring system. Insights from the new gravity imager will be used for volcanic hazards analysis and to demonstrate the importance of gravity to problems of societal relevance. A successful implementation of NEWTON-g will open new doors for geophysical exploration and will shift the focus of gravimeter manufacture from North America to Europe.
