Page 193 - The intensity of an earthquake at first decreases rapidly as the disturbance radiates ; subsequently it decreases more slowly. 8. A curve of intensities deduced from observations at a sufficient number of stations would furnish the means of approximately caclulating an absolute value for the intensity of an earthquake.
Page 12 - ... the broken-line in Fig. 84, is about 20 miles long, 15 miles wide and contains about 240 square miles, its centre coinciding with London Bridge. The shock was unusually strong for so small a disturbed area. Some damage was caused by it, but hardly sufficient to entitle the shock to the intensity 8. A slaughter-house with a hayloft over it was thrown down in Southwark, part of a chimney in Leadenhall Street, a chimney in Billiter Square, several chimneys Fig. 84.

Page 219 - Probably we shall not be far wrong if we attribute the recent earthquake in Essex to one or more subterranean rents produced by shrinkage, which led to no material shifting of the rocks, and which, owing to the tenacious nature of the subsoil at Colchester, chiefly London Clay, did not manifest itself in any conspicuous manner at the surface.

The dogs were sensible of it, and some of them howled in an uncommon manner, and fish jumped half a yard above water. The shock was felt at Cheshunt, Hertford, Ware, Copthall, near Epping, and Beckenham in Kent. March 14. The King went to the House of Peers, and passed the following bills: The bill for continuing and granting to his Majesty certain duties upon malt, mum, cyder, and perry, for the service...

On account of this difference in period, whilst one portion of a building is endeavouring to move towards the right, another is pulling towards the left, and, in consequence, either the bonds which join them or else the masses themselves are strained or broken.
