Earthquake early warning would be improved if the final size of an ongoing earthquake could be predicted early in the rupture process. Previous research relies largely on parameters derived from seismic waveforms, resulting in widely varied estimates of how much of the rupture must be complete before final sizes can be predicted. We demonstrate...

The Finite-Fault Rupture Detector (FinDer) algorithm computes rapid line-source rupture models from high-frequency seismic acceleration amplitudes (PGA). In this paper, we propose two extensions to FinDer, called FinDerS and FinDerS+, which have the advantage of taking into account a geological property of the source fault, its structural...

Large earthquakes, such as Wenchuan in 2008, Mw 7.9, Sichuan, China, provide an opportunity for earthquake early warning (EEW), as many heavily shaken areas are far (⁠∼50  km⁠) from the epicenter and warning times could be sufficient (⁠≥5  s⁠) to take preventive action. On the other hand, earthquakes with magnitudes larger than ∼M 6.5 are...

In December 2018, the NASA InSight mission deployed a seismometer on the surface of Mars. In preparation for the data analysis, in July 2017 the Mars Quake Service initiated a blind test, in which participants were asked to detect and characterize seismicity embedded in a one Earth year long synthetic dataset of continuous waveforms. Synthetic...
