International Association Of Seismology And Physics Of The Earth’s Interior

IASPEI endorses the study of earthquakes & additional seismic sources, the proliferation of seismic waves, the Earth's internal structure, properties, and processes. Scientists take part in IASPEI initiate & co-ordinate research & scientific exchanges that demand co-operation amongst countries. Work on specific topics is carried out through commissions, sub-commissions, committees and working groups formed to meet specific needs of new, exciting problems as they emerge. Seismology has its roots in observations of earthquakes and earthquake-generated ground motion. The worldwide system of seismograph stations envisioned by the pioneers of the science is now a reality, a reality that is frequently upgraded and expanded as technology improves. A global system of broadband seismographs with high dynamic range is in place. This is supplemented by many regional and local networks capable of high-resolution monitoring of the frequent smaller earthquakes in seismically active places. However, all of these high-quality data are of little value until they have been brought together for analysis and the results of these primary analyses made available to all researchers and users of seismological information. This requires well-equipped data centres that can carry out the determination of the times, locations, magnitudes, and other general characteristics of the events; archive the results of these analyses in accessible form; and provide a mechanism by which these results and the original data are distributed. Through commissions and working groups IASPEI has played an essential role in the promotion of proper data management and the formulation of standards for data treatment. Looking toward the 21st Century, the primary IASPEI emphasis in evaluating new approaches to acquiring, processing, and distributing seismological data is the automatic performance of traditional tasks in as close to real time as current technology permits. IASPEI's' structure and its many scientific activities are categorised by the following themes: Earth Structure and Geodynamics; Earthquake Generation Process – Physics, Modelling and; Monitoring for Forecast; Earthquake Hazard, Risk and Strong Ground Motion; Earthquake Source; Mechanics; Education and Outreach; Heatflow; Seismological Observation and Interpretation; Tectonophysics and Crustal Structure; Regional Seismological Commissions in Africa (AfSC), Asia (ASC), Europe (ESC) and Latin America and the Caribbean (LACSC).
