EARTHQUAKES AND SHORTWAVE RECEPTION
Experts in tlio past have already expressed the opinion that inexplicable interference phenomena in the reception of short-wave stations might possibly be due to earthquakes. The recent llawkes Bay earthquake gave support to this surmise, several experimenters in widely separated parts; of the globe having reported on this. By the last English mail, further data was received by the chief radio engineer of Philips Lamps (N.Z.), Ltd., Wellington, checking the observations of New •Zealand experimenters.. The principal effect is apparently the raising of the skip distance, so that a' wave-length normally very effective over a given- distance at a particular hour becomes practically useless, the signal being reflected right over the receiving station ■ instead ■of ■■ being reflected down on to it. ...■ • . ;.
