Short summary
Global navigation satellite system signals are used to measure the perturbations induced in the ionosphere by earthquakes related to volcanic eruptions. The study uses data from ground stations and satellites measuring the signals reflected on the ocean or during radio occultation. The results shows a small correlation, but given the small magnitude of the earthquakes, it is difficult to apply this concept to any practical application that finds earthquake proxies in ionospheric perturbations.
