The changing face of Mount Etna's summit area documented with Lidar technology

1986–2007 period amounts to 112 ± 12 10 6 m 3 ,a t a mean annual rate of 5.3 10 6 m 3 . The comparison of the various surveys furthermore emphasizes the levels of accuracy and resolution of the different techniques applied. The Lidar technology used in 2007 allows production of high-precision maps in near-real-time, facilitating work concerning environmental hazards such as numerical simulations of, e.g., lava flows.
