Marie Chaput,


This dataset contains the structural data measured on Piton des Neiges volcano (La Réunion island) from 2009 to 2016. The data are composed of intrusion data and of brittle deformation structures found in the field. Most of the data were measured in highly eroded areas in the central part of the edifice called the cirques: - Cirque of Cilaos : files PDN_CIL - Cirque of Salazie: files PDN_SAL - Cirque of Mafate: files PDN_MAF Other data were measured on the outer flanks of the edifice : files PDN_FLKS. Data are provided in two formats : .csv and .wtd. This latter can be opened with the free TENSOR program ( PLEASE DOWNLOAD THE "READ ME FIRST" TEXTFILE FOR A COMPLETE DESCRIPTION OF THE DATA FILES Related articles : Chaput, M., Famin, V. and Michon, L., 2017.
