T1  - Coincident anomalies of seismic attenuation and electrical resistivity beneath the southern Bolivian Altiplano plateau
N2  - Reassessment of local earthquake data from the ANCORP seismological network allowed the calculation of 3D attenuation (Q(p)) tomographic images of crust and upper mantle beneath the southern Bolivian Altiplano around 21degrees S. The images reveal a low-Q(p) middle and lower crust and a moderate-Q(p) upper mantle beneath the southern Altiplano. Beneath the recent magmatic arc, Q(p) is not significantly decreased at this latitude. The distribution of crustal Q(p) coincides with the variation of electrical resistivity, thus limiting the possible mechanisms causing the anomalies. Our findings support the hypothesis that partial melts in middle and lower crust beneath the Altiplano are present on a large scale. We see no evidence for a shallow asthenosphere beneath the southern Altiplano

T1  - The 2015 Illapel earthquake, central Chile: A type case for a characteristic earthquake?
JF  - Geophysical research letters
N2  - On 16 September 2015, the M-W = 8.2 Illapel megathrust earthquake ruptured the Central Chilean margin. Combining inversions of displacement measurements and seismic waveforms with high frequency (HF) teleseismic backprojection, we derive a comprehensive description of the rupture, which also predicts deep ocean tsunami wave heights. We further determine moment tensors and obtain accurate depth estimates for the aftershock sequence. The earthquake nucleated near the coast but then propagated to the north and updip, attaining a peak slip of 5-6 m. In contrast, HF seismic radiation is mostly emitted downdip of the region of intense slip and arrests earlier than the long period rupture, indicating smooth slip along the shallow plate interface in the final phase. A superficially similar earthquake in 1943 with a similar aftershock zone had a much shorter source time function, which matches the duration of HF seismic radiation in the recent event, indicating that the 1943 event lacked the shallow slip.
