The global CMT project 2004–2010: Centroid-moment tensors for 13,017 earthquakes
TL;DR: For the period 2004-2010, 13,017 new centroid-moment tensors were reported as mentioned in this paper, and the results are the product of the global centroidmoment-tensor (GCMT) project, which maintains and extends a catalog of global seismic moment tensors beginning with earthquakes in 1976.

TL;DR: Tsunami and geodetic observations indicate that additional slow slip occurred in the north over a time scale of 50 minutes or longer, and fault slip of up to 15 meters occurred near Banda Aceh, Sumatra, but to the north, along the Nicobar and Andaman Islands, rapid slip was much smaller.
Journal ArticleDOI
Anisotropic shear‐wave velocity structure of the Earth's mantle: A global model
TL;DR: In this paper, a 3D model of the anisotropic shear wave velocity in the Earth's mantle has been proposed, which combines a large data set of surface wave phase anomalies, long-period waveforms, and body wave travel times to construct a three-dimensional model.
Journal ArticleDOI
The Italian CMT dataset from 1977 to the present
S. Pondrelli,Simone Salimbeni,Göran Ekström,Andrea Morelli,Paolo Gasperini,Gianfranco Vannucci +5 more
TL;DR: The INGV-Harvard European-Mediterranean Regional Centroid Moment Tensor (RCMT) catalog as mentioned in this paper collects solutions routinely computed since 1997 for earthquakes with moderate magnitude (45 ≤ M ≤ 55 ) in the Mediterranean region.
Journal ArticleDOI
The unique anisotropy of the Pacific upper mantle
Göran Ekström,Adam M. Dziewonski +1 more
TL;DR: In this paper, the authors present results from a global three-dimensional tomographic model of shear-wave velocity which shows that the uppermost mantle beneath the central Pacific Ocean is considerably more complicated than this simple model.
