Abstract
A number of seismic methods exist to image the lithosphere below a
collection of receivers, using distant earthquakes. In the current
practice, especially mode-conversions in teleseismic phases are
utilized. We present a new method that takes advantage of the
availability of global phases. This method is called global-phase
seismic interferometry (GloPSI). With GloPSI, zero-offset reflections
are extracted from reverberations near the array caused by global
seismicity. We exemplify GloPSI with data from the Hi-CLIMB experiment
(2002-2005) and migrate the obtained reflection responses. This
results in a 800 km long reflectivity profile through the Himalayas
and a large part of the Tibetan Plateau.
