TitleLetter from John Milne, Shide Hill House, Shide, Newport, Isle of Wight, to [Joseph] Larmor
CreatorMilne; John (1850-1913); British geologist and seismologist
RecipientLarmor; Sir Joseph (1857-1942); Irish theoretical physicist
Date30 April 1905
DescriptionEarthquakes are like American society - there are upper and lower classes but no middle. The first are represnted by dislocations of 100 miles in length and bodily displacements the size of English counties. They 'shake the world & make its skin behave like a raft on an ocean swell'. The second are adjustments on the line of faults and make areas like counties vibrate. He describes the effects, saying it is rare to detect a vertical component. There are 30,000 per year and England contributes only six. Larger events are about 50 to 100 per year, at a depth of about 3,000 feet. What he knows of them comes from a Wiechart pendulum at 1100 metres. Yesterday he had ten visitors making enquiries, but the flood of enquiries after the Indian disaster is abating.
