Abstract
AN earth tremor approximately of scale 4½ on the modified Mercalli scale (scale 5—felt by nearly everyone, many awakened, some dishes, windows, etc., broken, a few instances of cracked plaster, unstable objects overturned; disturbance of trees, poles and other tall objects sometimes noticed; pendulum clocks may stop) in the epicentral region occurred on December 30, 1944, about 12.35 a.m. G.M.T. It was recorded on Mr. J. J. Shaw's seismograms at West Bromwich, and here the record lasted about two minutes. The seismograph at Stonyhurst College Observatory was unhinged by the shock so that the full record was not obtained. Reports are not yet to hand from other observatories. The tremor was felt by people over a radius of approximately a hundred miles, and was reported from Carlisle, Newcastle, Norfolk, Derby and intermediate places. No damage or casualties have been reported. So far as can be ascertained there was no noise associated with the tremor. In the north of England this was the greatest tremor since the North Sea earthquake (epicentre latitude 53·7° N., longitude 1·3° E.) of June 7, 1931. A somewhat greater tremor shook Scotland and England on October 23, 1839, when the epicentre was near Comrie.
