JTC-IUGG

About

The Joint Tsunami Commission (JTC) of the International Union of Geodesy and Geophysics (IUGG) is an international group of scientists concerned with various aspects of tsunamis, including an improved understanding of the dynamics of generation, propagation, and coastal run-up and the consequences to society of the tsunami hazard. Tsunamis are generated by various submarine processes such as earthquakes, volcanic eruptions, and submarine landslides, so that research is necessarily interdisciplinary, requiring studies that include the fields of seismology, volcanology, marine geology and geophysics, and hydrodynamics. 

The Joint Tsunami Commission is jointly sponsored by IASPEI, IAPSO and IAVCEI. It was established at the 12th General Assembly of IUGG in Helsinki, Finland in 1960 to promote the exchange of scientific and technical information about tsunamis among nations concerned with the tsunami hazard. Since then, the Commission has held 32 Tsunami Symposia, both as part of IUGG General Assemblies (GA) and independently in alternate years in the form of Internationla Tsunami Sympousium (ITS ) as listed below.
