Earthquakes — Mr. Hayes on Seismology

Earthquakes

Mr. Hayes on Seismology

At the Maths. and Physics Society meeting on Thursday, July 2, Mr. R. C. Hayes, Acting-Director of the Dominion Observatory covered the field of the recording of earthquakes, both from a historical and practical point of view. His lecture was enjoyed by the relatively large audience, and was made even more interesting by the large number of lantern slides shown.

After giving a brief history of the science of "Sscismology" in New Zealand, the lecturer went on to describe the work carried on both at Kelburn, and throughout New Zealand by the Dominion Observatory, and the various observation stations, in recording seismic data. The different types of seismic waves were described, and the method of determining the distance of a disturbance from an observation station was outlined. Following a brief history of the development of scismometers and seismographs, Mr. Hayes described the different types now in use, and concluded by showing how the graphs obtained were interpreted.

After a herty vote of thanks had been acourded the speaker, the meeting adjourned to supper.
