Abstract
DR. H. C. VERNEY has collected macroseismic data concerning the Skipton earthquake of December 30, 1944 (Trans. Leeds Geol. Assoc, 6, No. 2; 1948), which shows that the earthquake had an intensity 7 on the Davison scale at the centre of greatest disturbance near the Gargrave Fault. In the central area subsurface drains were broken, and damage was caused to a bridge. York was just within isoseismal 5, and Lincoln, Manchester and Carlisle were within isoseismal 4. Dr. Versey relates the centre of disturbance to the Craven Faults near the margin of the rigid block of north-west Yorkshire with its early Palaeozoic and possibly pre-Cambrian basement rocks. Previous shocks at Kendal (March 17, 1871), Wetherby and York may also have been connected with the faulted boundaries of this rigid block. Sound phenomena associated with\he Skipton earthquake were heard by various observers, particularly those situated inside isoseismal 6, who compared the sounds with the rumbling of vehicles or the rushing of a strong wind.
