DOI: 10.1002/2017jb014025
Abstract: Real-time ground motion alerts, as can be provided by Earthquake Early Warning (EEW) systems, need to be both timely and sufficiently accurate to be useful. Yet how timely and how accurate the alerts of existing… read more here.

DOI: 10.1007/s00024-017-1477-2
Abstract: Atmospheric processes, ranging from microscale turbulence to severe storms on the synoptic scale, impact the continuous ground motion of the earth and have the potential to induce strong broad-band noise in seismological recordings. We designed… read more here.

DOI: 10.1007/s00024-019-02176-6
Abstract: Observed ground-motion intensity for six earthquakes of Mw = 6.0–6.2 that occurred in China’s North–South Seismic Zone (NSSZ) was compared with predicted medians from the BSSA14 model. The resulting between-event (δBe) and within-event (δWes) residuals for peak… read more here.

DOI: 10.1007/s10518-017-0110-1
Abstract: Near-field recordings are very sensitive to the spatiotemporal details of the rupture process while far-field signals show the signature of the overall “point-source” earthquake mechanism. Near- and far-field recording ranges are dependent on the event… read more here.
