Development of a google maps-based tool to quickly visualize a large gravity data set collected at etna volcano (Italy)

Geophysical measurements provide a massive data source to investigate the behaviour of active volcanoes like Ml Etna (Sicily, Italy). Here we present a new interface to visualize gravity variations, observed through time-lapse measurements, based on the Google Maps service, a choice motivated by its ease of use and the user-friendly interactive environment it provides. The tool allows to choose among the benchmarks of the Etna's gravity network, as well as to quickly visualize the gravity data since 1994. The integration of these measurements into a coherent visualization framework is important for their practical exploitation, providing a powerful environment for a quick and efficient processing of data time series.
