Abstract
THIS great earthquake is being studied by officers of the Geological Survey of India. Their investigations in the central area are expected to last for several weeks longer, and their results will be published by the Survey at an early date. In the meantime, three papers of some interest have appeared. Sir E. Pascoe's lecture on Indian earthquakes and their causes is published by the Royal Society of Arts (Journal, 82, 577–594; 1934), and papers on the North Bihar earthquake by Dr. M. S. Krishnan and Dr. S. K. Banerji in Current Science (2, 323–326, 326–331; 1934). From the observations so far made, it seems, according to Dr. Banerji, that the earthquake fault reaches from Motihari to Monghyr, a distance of about 135 miles. There is probably also a second fault, branching from near the middle of the latter and running in the direction of Purnea. Most of the seismographs in India were thrown out of action by the shock, but good records were obtained, and are here reproduced, at Colaba (Bombay) and Agra. From the great preponderance of the surface waves compared with the primary and secondary waves, Dr. Banerji concludes that the focus was at a very slight depth below the surface. All three writers agree in attributing the earthquake to a disturbance of the isostatic compensation.
