The effect of wind and plume height reconstruction methods on the accuracy of simple plume models — a second look at the 2010 Eyjafjallajökull eruption

Dürig, Tobias; Guðmundsson, Magnús T.; Ágústsdóttir, Thorbjörg; Högnadóttir, Thórdís; Schmidt, Louise (Springer, 2022-02-28)

Real-time monitoring of volcanic ash plumes with the aim to estimate the mass eruption rate is crucial for predicting atmospheric ash concentration. Mass eruption rates are usually assessed by 0D and 1D plume models, which are fast and require only a ...
Eruption dynamics of Anak Krakatau volcano (Indonesia) estimated using photogrammetric methods

Hochfeld, Isabell; Hort, Matthias; Schwalbe, Ellen; Dürig, Tobias (Springer, 2022-07-08)

Analyzing video data from an uncrewed aerial vehicle (UAV) of two short-lived dome building events at Anak Krakatau volcano (Indonesia), we determine vertical and horizontal movements of the dome surface prior to explosions, as well as initial eruption ...
