    Description: We use a novel technique named global-phase seismic interferometry (GloPSI) to image the lithospheric structure, and in particular the Moho, below two parallel north-south transects belonging to the GANSSER network (2013–2014). The profiles cross the Himalayan orogenic wedge in Bhutan, a tectonically important area within the largest continent-continent collision zone on Earth that is still undergoing crustal thickening and represents a challenging imaging target for the GloPSI approach. GloPSI makes use of direct waves from distant earthquakes and receiver-side reverberations with near vertical incidence. Reflections are isolated from earthquake recordings by solving a correlation integral and are turned into a reflectivity image of the lithosphere below the arrays. Our results compare favorably with first-order features observed from a previous receiver function (RF) study. We show that a combined interpretation of GloPSI and RF results allows for a more in-depth understanding of the lithospheric structure across the orogenic wedge in Bhutan.

    Description: The mountain chains of the Central Mediterranean (the Apennines, the Alps, the Dinarides, the Albanides, and the Hellenides) are shaped by complex tectonics arising from the motion and collision of several microplates. Intense onshore and offshore seismic activity puts the rich cultural heritage characterising the entire region at risk. A better understanding of the lithospheric structures and knowledge of the interaction between different tectonic units is key to unraveling the processes underlying seismic activity in this area. In recent years, top-quality seismological data from several groundbreaking experiments have yielded new insight into the orogenic systems of the region (e.g., IberArray, AlpArray, and its complementary seismic experiments, or the “THALES WAS RIGHT” EU project). Similar projects are planned to cover other parts of this critical region, for example, AdriaArray, which will cover the Adria microplate and the Balkans with a dense seismological array.
