Friday Photo (89) – Satellite Monitoring of Volcanoes

In order to monitor the earth movements in the Phlegraean Fields, near Naples, the Osservatorio Vesuviano, together with other national and international research institutions, has installed two artificial reflectors which can monitor slow ground movement over specific features or locations of interest. The parabolic antenna is used to transmit the data to a geo-stationary satellite, which then tr ...[Read More]

Guest Blog: A Summer of Volcanic Observation in Ecuador (1)

David Litchfield holds an MA in Social Work and has worked in this field for a number of years. However, experience of travel and living in Latin America led to the renewal of a long-forgotten interest in geosciences and especially in volcanism. On return to the UK he completed a second undergraduate degree in Geosciences with the Open University and is currently studying part-time for an MSc in G ...[Read More]

Friday Photo (88): Volcanic Mud Pits

The Solfatara volcanic crater at Pozzuoli, part of the Campi Flegrei volcanic area, has many fumaroles and mud pools. The bubbling mud pits are created by rainwater and vapor condensation, which mix with the clay material present on the surface of the volcanic crater. The gas composition which spews out from the mud pit is varying (H2S, N2O, H2O, CH4, He, C); the liquid composition is as rich (Bor ...[Read More]

Guest Blog: Mount Vesuvius Today

Christopher Dimech is a PhD researcher at University College London. We wrote about the Roman eruption of Vesuvius, and the consequences for Pompeii and Herculaneum, on our blog in June. Chris has spent some time at the monitoring station near mount Vesuvius, and here gives us an insight into the kind of research that goes on there. Italy is much better prepared for volcanic hazards today than it ...[Read More]
