Mt. Etna, the most active volcano in Europe, is extensively monitored by the Osservatorio Etneo (OE), of the Istituto Nazionale di Geofisica e Vulcanologia (INGV), using various geophysical sensors, including gravimeters. This paper focuses on the design and implementation of a system for storing continuous gravimetric data recorded by three permanent stations on Mt. Etna, powered by GWR iGrav Superconducting Gravimeters. These devices provide high-precision gravity measurements along with numerous internal and external parameters required for data correction and interpretation. The continuous data from these stations generate large datasets stored as daily ASCII-encoded TSF files, synchronized hourly on a central server. To optimize data storage and retrieval, a time series database...
