Description

3D distribution of the a and b parameters of the Gutenberg-Richter (GR) law. The analysis is presented in Gola G., Barone A., Castaldo R., Chiodini G., D'Auria L., Garcia-Hernandez R., Pepe S., Solaro G. & Tizzani P. "A novel multidisciplinary approach for the thermo-rheological study of volcanic areas: The case study of Long Valley Caldera", which has been submitted for possible publication in Journal of Geophysical Research - Solid Earth. For this purpose, we used a dataset consisting of more than 220,000 earthquakes from the NCEDC catalogue (NCEDC, 2014), spanning the interval 1978-2017 and located in the surroundings of Long Valley Caldera. We mapped the a and b values for a volume of 50×50×30 km3, over a grid of points having a regular spacing of 0.5 km.
