Examples of the facies that compose the 2014–2015 Holuhraun lava flow-field. The panels in the first and third columns show examples drawn from the UltraCam-Hp basemap (0.2 m/pixel) at the digitalizing scale of 1:800. The panels in the second and fourth column show a corresponding field-photo for each facies. (a) and (b) show examples of the rubbly facies; (c) and (d) show the spiny facies; (e) and (f) show the undifferentiated rubbly–spiny facies; (g) and (h) show locations within the shelly facies; (i) and (j) show the pāhoehoe facies; (k) and (l) show the flat-lying–knobby facies; (m) and (n) show the vent-proximal edifice facies; and (o) and (p) show the channel interior facies.
🌋 Did you know #lavaflows are more complex than just two types, the classic ʻaʻā and pāhoehoe? Voigt et al's study of #Holuhraun eruption found more. See their dataset & article at doi.org/10.25422/azu... & doi.org/10.1016/j.jv.... Image: CC BY-NC-ND 4.0 #OpenData #OpenScience #PlanetaryScience
