Career in England (1895–1913)
After a fire on 17 February 1895 destroyed his home, observatory, library, and many of his instruments, Milne resigned his posts on 20 June 1895 and returned to England with his Japanese wife, settling at Shide Hill House, Shide, on the Isle of Wight, where he continued his seismographic studies. He was made a professor emeritus of Tokyo Imperial University.
He was elected a Fellow of the Royal Society in 1887 and persuaded the Society to fund 20 earthquake observatories around the world, equipped with his horizontal pendulum seismographs. His network initially included seven in England, three in Russia, two in Canada (one in Toronto and one in Victoria, British Columbia), three on the east coast of the United States, and one in Antarctica, eventually growing to total forty worldwide. These stations sent their 'station registers' to Milne, where the data formed the basis of Milne's researches. For the next 20 years, Milne's seismological observatory was the world headquarters for earthquake seismology. In 1898, Milne (with W. K. Burton) published Earthquakes and Other Earth Movements, which came to be regarded as a classic textbook on earthquakes.
The need for international exchange of readings was soon recognised by Milne in his annual "Shide Circular Reports on Earthquakes" published from 1900 to 1912. This work was destined to develop in the International Seismological Summary being set up immediately after the First World War.
He delivered the Bakerian Lecture to the Royal Society in 1906 entitled Recent Advances in Seismology and was awarded their Royal Medal in 1908.
Milne died of Bright's disease on 31 July 1913 and, after a service in St. Paul's Church, Newport, was buried in the civic cemetery to the north of the church. His Japanese wife Tone returned to Japan in 1919 and died in 1926.
To mark the 100th anniversary of Milne's death, a public artwork has been commissioned for Little London near the harbour at Newport. The local Parish Council is providing a detailed explanatory board at Shide.
