Earthquakes during February 1940

    Abstract

    AT Kew, Basle, Chur, Zurich and Neuchatel the registrations of earthquakes tended to show that the earth was seismologically less active than normal during February 1940. At Kew only ten notable shocks were registered during the whole month, the greatest being the three of February 7, 20, and 29. At the Swiss observatories, seventeen shocks were registered, though only nine sets of readings were sufficiently clear to obtain epicentral distances, two of these being doubtful. Distant earthquakes giving consistent readings were those of February 7, 23, and 29, the four others being much nearer to the Swiss stations. Fairly good readings were obtained at Kew for the earthquake of February 23 and at the Swiss observatories for that of February 20, but epicentral distances were not determined.
