Earthquake traces recorded by Milne's seismograph, 1901.

Diagram entitled 'Earthquake Mesages', showing seismograph traces of three earthquakes recorded by John Milne. Milne (1851-1913) was a brilliant English geologist, regarded as the founding father of seismology, who lived and worked in Tokyo, Japan. He retired to Shide on the Isle of Wight, in southern England, where he set up seismographs at his home. On 9th August 1901, he recorded these three earthquakes on a machine of his own design. All three earthquakes occurred in various locations in the Pacific, on the other side of the world.
