A delegation of 11 SEG members visited the People’s Republic of China (PRC), September 5–27, 1979, in exchange for a visit by an equal number of PRC geophysicists to the U.S., November 1–20, 1979. Represented were 7 U.S. petroleum and 4 geophysical service companies. Facilities visited were the Geophysical Research Institute and an instrument factory in Peking; Electronic Computer Center and Geophysical Research Institute in Cho Hsien, 60 km south of Peking; Shengli oil field on the Yellow River delta; Marine Branch of the Geological Exploration Corp. in Shanghai; Southwest Branch of the China Petroleum Corp. in Chengtu; and China Petroleum Corp. offices in Canton. Delegation members presented papers at each facility visited except at the instrument factory in Peking. Data processing computer systems (Chinese, French, and U.S.) were toured at the computer center and also at the Shengli oil field. The visit to the latter also included a tour of the oil field and a geochemical laboratory. A highlight was a visit to a seismic field party operating near Chungking. Group discussions followed presentations of papers by delegation members. Generally, these consisted of a description by PRC geophysicists of current seismic exploration efforts and associated problems peculiar to the areas being explored. Delegation members then endeavored to answer specific questions and offer potential solutions to problems encountered. A wide range of topics was involved, covering seismic data acquisition, processing, and interpretation. Of special interest were (1) determination of lithology, (2) reef exploration, (3) operations in areas of rugged topography, (4) deconvolution, (5) modeling and migration, and (6) static time corrections. The delegation found that PRC geophysicists generally are aware of latest techniques in seismic data acquisition and processing but are lacking in the effective application of these. Undoubtedly, this is due to incomplete acquisition of modern field equipment and data processing systems.

Abstract As the earliest institute in Turkey dedicated to locating, recording, and archiving earthquakes in the region, the Kandilli Observatory and Earthquake Research Institute (KOERI) has a long history in seismic observation, which dates back to the installation of its first seismometers soon after the devastating Istanbul earthquake of 10 July 1894. For over a century, since the deployment of its first seismometer, the KOERI seismic network has grown steadily in time. In this article, we present the KOERI seismic network facilities as a data center for the seismological community, providing data and services through the European Integrated Data Archive (EIDA) and the Rapid Raw Strong-Motion (RRSM) database, both integrated in the Observatories and Research Facilities for European Seismology (ORFEUS). The objective of this article is to provide an overview of the KOERI seismic services within ORFEUS and to introduce some of the procedures that allow to check the health of the seismic network and the quality of the data recorded at KOERI seismic stations, which are shared through EIDA and RRSM.

<p>There has been considerable development of seismic detectors over the last 80 years. However, there is still a need to further develop new earthquake exploration and data acquisition systems with high precision. In particular, for China to keep up with the latest technology of these systems, it is important to be involved in the research and development, instead of importing systems that soon fall behind the latest technology. In this study, the features of system-on-a-programmable-chip (SoPC) technology are analyzed and used to design a new digital seismic-data acquisition station. The hardware circuit of the station was developed, and the analog board and the main control data-transmission board were designed according to the needs of digital seismic-data acquisition stations. High-definition analog-to-digital converter sequential digital filter technology of the station (cascade integrator comb filter, finite impulse response digital filter) were incorporated to provide advantages to the acquisition station, such as high definition, large dynamic scope, and low noise. A specific data-transmission protocol was designed for the station, which ensured a transmission speed of 16 Mbps along a 55-m wire with low power consumption. Synchronic acquisition was researched and developed, so as to achieve accuracy better than 200 ns. The key technologies were integrated into the SoPC of the main control data-transmission board, so as to ensure high-resolution acquisition of the station, while improving the accuracy of the synchronic acquisition and data-transmission speed, lowering the power consumption, and preparing for the follow-up efforts to tape out.</p>
