Analysis of pulsatory activity of the 2021 Tajogaite eruption - Supplement dataset of Bonadonna et al. (2023), Front. Earth Sci. 11:116607.3

This repository contains the data processed for the analysis of pulsatory volcanic activity of the 2021 Tajogaite eruption in La Palma. The dataset includes the statistical analysis of the repose time between explosions of various analysed sub-datasets. Pulsatory activity has been characterized in terms of the log-logistic distribution parameters and its correlation with magma viscosity by Dominguez et al. 2016. Following the same methodology here we present the corresponding log-logistic parameters and viscosity estimations for all Tajogaite sub-datasets.

This dataset is associated with the following scientific publication, including supplementary material of grainsize and plume dynamics processes.

Content & Structure

Three folders organised as follows:

•    'stationnarity_analysis' : folder containing all correlograms and stationarity tests of the independent and stationary time series according to Dominguez et al. (2016) methodology.
• 'distribution_results' : folder containing all the hostograms of the sub-datasets analysed.
• 'LP_log_logistic_viscosity' : Excel file with log-logistic distribution parameters and viscosity estimations for all the sub-datasets analysed.
