Paul Morin from the University of Minnesota (USA) gave a
presentation on a new digital elevation model of the entire Arctic region north
of 60°N, known as the ArcticDEM, created from satellite data during the US
chairmanship of the Arctic Council in 2015–17. Morin led the work on the new

This graph shows the ice-surface lowering (subsidence) of the eastern Skaftá ice-cauldron in Vatnajökull ice cap in October 2015. Vertical displacement (m) was monitored by near real time presentation of data from a GPS station, mounted in the middle of the cauldron. The maximum elevation above sea level, top left (hæð), refers to the zero value on the y-axis; while such value top right

million m3 and it originated from the southeast margin of the inner caldera,
triggering a large tsunami into the lake. The tsunami wave inundated the shores all around the lake,
reaching up to 40 m elevation above the lake level. The seismic waves produced by the landslide were
recorded by most of the IMO's seismic stations in Iceland and allowed to establish the onset time
around 23:24 UTC.
