earthquake and tectonic studies

The history of .minoractivity is covered largely in a series of references listed in Serial 609, in recent reports of the United States Coast and Geodetic Survey, and in the Bulletin of the Seismological Society of America. 1 The last two references give very detailed information for all California earthquakes.The last one contains all of the information appearing in the early catalogs published by the Smithsonian Institution.Earthquakes of volcanic origin in the Hawaiian Islands are not included.Complete reports are published by local seismological institutions.Earthquakes adjacent to the United States and felt within its borders are described only in a general way when detailed descriptions are published elsewhere.Cooperation of investigators solicited.In order that these publications may be as complete as possible in the more important details of earthquakes and in references, it is desired that investigators cooperate to the fullest extent, as such cooperation will be to the mutual advantage of everyone concerned.The Survey is willing to furnish investigators all information at its disposal, consisting principally of seismographic records and postcard questionnaires obtained in many instances through special canvassing of affected areas.In return it is requested that advance notices be furnished of results obtained so that abstracts and references may be inserted in these reports.An advance notice of a planned investigation might save considerable overlapping of effort and would give wider publicity to the work of the investigator.Earthquake information services.The Coast and Geodetic Survey maintains a field party in San Francisco, the Seismological Field Survey, which in addition to other duties collects earthquake information in the Pacific Coast and Western Mountain States.In this work the seismological station of the University of California, Berkeley (Dr.Perry Byerly in charge), and the Seismological Laboratory of the California Institute of Technology, at Pasadena (Dr.Beno Gutenberg in charge), cooperate actively
