... seismic stations using earthquakes or ambient seismic noise data (including microseisms and hum). Many achievements have been made based on earthquake data, for example, global imaging with body waves ( Dziewonski and Woodhouse, 1987 ), surface waves ( Ekström et al. , 1997 ), or jointly with multiple...

... and thermal structure of the lithospheric system. Mapping of earthquake‐defined Benioff zones combined with tomographic imaging reveals the presence of an ∼240 km long east–west‐striking slab tear, named here the Caldas tear. The proposed Caldas tear separates a zone of shallow, 20°–30°‐dipping, southeastward...

Stationary broadband instruments are required for an accurate representation of teleseisms at low...
