The explosive activity of the 2021 Tajogaite eruption (La Palma, Canary Islands, Spain)

The dataset includes the results of the image analyses of the high-speed videos of the 2021 Tajogaite eruption of Cumbre Vieja volcano, La Palma, Canary Islands, Spain. The results of the Optical Flow analyses include 123 files, one for each video, with the name indicating the date and time (UTC) of the video in the DDMMYYYY_HHMM format and the frame interval at which the analysis was performed. These data are grafically presented in the Supporting_Atlas file that accompanies the manuscript by the same title as the dataset and in part in Figure 6. The files named 'all_info' and 'all_info_types' collect all the metadata of the videos and, the latter one, also the division in the different activities we identified, plus the results of the pulse freqency and average maximum velocity analyses that appear in Figure 7 of the manuscirpt. The results of the grain size distribution, size and rise velocity of the pyroclasts, and mean rise speed and mass flux are reported for 12 selected videos with the the same name format and the suffix '_sizevel'. These data appear in Figure 8 of the manuscript.
