摘要: In the present paper, we analyse ground tilt and seismicity at Campi Flegrei caldera Ischia Island, two volcanic areas located in south of Italy. These have been well studied for many years from a petrological, volcanological geophysical view point. Moreover, due to high seismic risk populations living there, they are continuously monitored by networks geochemical sensors. We summarize most important results that obtained so far, concerning observations relationships between activity anomalies, focusing on time interval 2015–2018. First, detailed description tiltmeter both investigated areas, as their development improvement over has enabled quality data collection. From joint analysis borehole signals, often notice concurrence pattern variations occurrence seismicity. major anomalies appear be linked with rate energy volcano-tectonic earthquakes, exogenous phenomena like solid Earth tides hydrological cycles. The potential applicability other systems. Our findings show how use can contribute better understanding dynamics volcanoes.
