A group of scientists and researchers working out of the University of Glasgow have developed a high-tech device, dubbed the Wee-g, that is essentially a compact gravimeter capable of detecting gravitational phenomena that could be used to predict potential earthquakes.

This gravimeter makes use of a silicon spring that is 10 times thinner than a human hair and, combined with a square sensor, is capable of detecting even the most subtle and minute changes in the planet's gravitational field.

This compact gravimeter device has a whole range of possible implications. It could be used to conduct gravity measurement initiatives with an aim to informing geophysical exploration and surveying, and it could also be used around volcanoes to detect magma activity before an eruption, potentially boosting early warning systems.
