Database of Quaternary volcanic vents in the Turkana Depression

This dataset contains the coordinates of all the Quaternary volcanic vents charactserising the Turkana Depression, East Africa. Vent mapping relied on 3 sources: (1) analyzing SRTM digital elevation models with a cell size of 30 m (http://www2.jpl.nasa.gov/srtm/), (2) interpreting panchromatic satellite images with pixel resolution of 2.5-20 m by using Google Earth (http://earth.google.com/), and (3) integrating previous work by Mazzarini and Isola (2022). Vents with a diameter smaller than a few pixels (i.e., <60 m), disrupted vents (vents without a well-preserved morphology), and vents covered by younger volcanic products have been filtered out. The coordinates are georeferenced in the ESPSG 4326 WGS84 system. The dataset is a supplementary material for the manuscript 'Control of gravitational potential energy on the distribution of off-rift volcanic activity in the Turkana Depression, East African Rift' by Corti et al. The figure shows the volcanic vents in the different volcanic fields. Green dots illustrate in-axis volcanoes (Em: Emuruangogolak, Ba: Barrier, CI: Central Island, Ko: Korath range, Na: Namarunu, Si: Silali, SI: South Island); black dots illustrate off-rift volcanoes (As: Asie volcanic field; DD: Dilo-Dukana volcanic field; HH: Hurri Hills volcanic field; Ma: Marsabit volcanic field; Me: Mega volcanic field). LT: Lake Turkana; RR: Ririba Rift.
