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

Where 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

Inge Lehmann and the rise of international seismology, 1925-1970

Danish seismologist Inge Lehmann (1888-1993) is best known for presenting the first evidence of the Earth’s inner core in 1936. Her active research career as a seismologist began in 1928, continued well into the 1970s, and earned her the reputation as “the grande dame” of modern seismology
