Arctic geopolitics and the beginning of earthquake monitoring in Denmark and Greenland

Were there scientific or political reasons behind Denmark’s decision to establish its first seismological stations for earthquake monitoring? In a nation where earthquakes are few and of small magnitude, it is remarkable that since 1927 the Geological Survey of Denmark and Greenland (GEUS), and its predecessors back to the Danish Geodetic Institute have recorded seismological events from permanent stations in Denmark and Greenland and shared data through international data centres.
