TIPAGE Seismology

station map
Cross section through the Earth's crust and mantle in the Pamir. The Pamir mountains are located in the northernmost part of the India-Eurasia collision zone. In this collision zone occur both shallow and deep earthquakes (depicted as white dots). The deep earthquakes are caused by the subduction of lower Eurasian crust.

Summary
We study deep structures and geodynamic processes in the Tien Shan and Pamir collision zones, central Asia, with passive source seismic experiments in Kyrgyzstan and Tajikistan. In 2008, a total of 40 seismic stations were deployed predominantly along a 350 km long N-S profile and partly as a sparse 2D seismic network covering an area of 300x300 km of the central Pamir plateau. In 2009, the array was rearranged into a 2D network with higher station density. The proposed scientific tasks to study the crust and upper mantle with seismic methods include (i) teleseismic P and S receiver functions, (ii) shear wave splitting, (iii) location of local earthquakes and waveform inversion for source mechanism, (iv) seismic tomography using local and teleseismic earthquakes, and (v) tomography of surface waves and ambient noise.
