Monitoring Volcanic Hazards...Europe

Renewed volcanic activity at the Phlegrean Fields tracked by Envisat
Satellite images acquired by ESA’s Envisat satellite have revealed the volcanic region of the Phlegrean Fields, located in southern Italy near the city of Naples, has entered a new uplift phase.

Using Differential SAR Interferometry (DInSAR), scientists at the Institute for the Electromagnetic Sensing of the Environment (IREA) of the Italian National Research Council (CNR) mapped the changes in the caldera – a ring-shaped region which includes several volcanoes – and discovered the area has uplifted about 2.8 centimetres from 2005 to 2006.

Hot stuff – 15 years of satellite data over Mt. Etna
Using radar images acquired by ESA satellites from 1992 to 2006, scientists have for the first time been able to monitor the long-term behaviour of Mt. Etna, Europe's highest and most active volcano.
