Global Lithospheric Imaging using Earthquake Recordings (GLImER)
Date du début: 1 août 2012, Date de fin: 31 juil. 2016 PROJET  TERMINÉ 

The objective of the proposed project is to conduct a global survey of lithospheric interfaces using converted teleseismic body waves. Data from permanent and temporary seismic networks worldwide will be processed automatically to produce global maps of key interfaces (Moho, intra-lithospheric interfaces, lithosphere-asthenosphere boundary). The seismic results will be interpreted in conjunction with constraints from complementary fields of the earth sciences such as tectonics, geodynamics, petrology, and geochemistry. This will provide a unique view of how the properties of these interfaces vary between different tectonic environments and thus how the interfaces relate to geological processes at work in these various environments. The results will be distributed to the scientific community in the form of data products through an original web-based application. They will also be included in a public outreach program aimed at increasing public awareness about solid earth sciences.
