Historical Seismograms - Evidence from the AD 2000 Izu Islands ...

498 K. L. SuendsenDominican Republic. For some years, one station with three short-period instrumentshas been operated by the Instituto Geografico Universitario of the Universityof Santo Domingo. Records are available through the local office of theInter-American Geodetic Survey.Morocco. There has been at least one seismograph in operation by the Universityof Rabat since about 1934; all seismograms have been microfilmed.Cape Verde. The National Institute of Technical Investigation was given a seismographby the U.S.S.R., but was not yet in operation at the time of my visit(1980).Sierra Leone. The Geological Survey Department has a Chinese seismographwhich records six channels, but is used only for engineering purposes. There is noother history of seismic work in Sierra Leone.Ivory Coast. The Lamto station is well-known, though its equipment may not bethe best. The Director said he would be happy to operate any better equipment ifprovided to them. All their records will be available for microfilming and could behandled by observatory personnel.w. The French Office de la Recherche Scientifique et Technique Outre-mer(ORSTOM) organization used to operate a seismograph in Lome, but the site wasnoisy and recording was discontinued. The records were sent to the Paris office andpresumably can be copied there.Nineria. The Physics Department of the University of Ibadan has only one seismometerfor classroom work; similarly, the Physics Department of Ahmadu BelloUniversity. The latter would, however, be interested in operating a WWSSN station.Niger. The Bureau of Geological and Mining Research informed me that therehad never been any seismographs operating in Niger.Zaire. They have three seismographs located at Binza, Karavia, and (Bunia).They have a recurring problem getting photo paper and parts, so recording is intermittent.Copying of their records was not discussed, but they have technical staffwho could probably handle it.Zambia. The Geological Survey Department has a current cooperative programwith the University of Finland, but said that any old records would have beenobtained by the Goetz Observatory.Malawi. The Geological Survey Department cooperates with the Goetr Observatorywhich manages the station at the Blantyre airport. Any old recordings wouldhave been done by the Goetz Observatory.Mozambiaue. Four stations are located in Maputo, Nampula, Tete, and Changelane,all operated by a visiting Soviet group at the Meteorological Service. Copyingof the records was not discussed. No information was obtained on any earlier recordings.Botswana. There have never been any seismic stations operated in Botswana.The Geological Survey of Botswana is interested in starting one, especially in theOkavango area. They have been discussing this matter with a Swedish group.Lesotho. According to the Department of Physics of the University of Lesotho,no seismograph has ever operated in Lesotho.
