Abstract
Two earthquakes of considerable severity have been recorded by observatories in England recently. The first was recorded at Kew on April 21 at 4 h. 39 m. 56 s. (dilatation) and the second on April 23 at 16 h. 32 m. 24 s. G.C.T. The former is thought provisionally to have had an epicentre in northeastern Asia, and to have had a depth of focus of some 500 km.; its occurrence is confirmed by a message from Dr. O. Somville of the Royal Observatory at Uccle, Belgium.
