3D Models, Okmok Volcano
These models are of various volcanic cones inside Okmok volcano, Umnak Island, Alaska. This helicopter survey was collected in July 2021 part of the summer fieldwork with the AVERT (Anticipating Volcanic Eruptions in Real Time) at Lamont-Doherty Earth Observatory and the Alaska Volcano Observatory. Photos were taken using the Cannon Mark 6 EOS II, and the model was processed in Agisoft Metashape. Photos and model processed by Jasper Baur (photos for Cone D captured by Nick Frearson).
I now have models for Ahmanilix tuff cone for the 2022 and 2023 field season. These models will be used to calculate the erosion rate of the tephra cone inside Okmok caldera and help us quantify the likelihood for lahars.
