My current research focuses on how earthquakes start and how predictable their rupture development is. We use large amounts of data to obtain a robust description of the statistical characteristics of rupture onsets and ensuing rupture development. The insight that we gain from these analyses we can use for the design of real-time damage mitigation strategies: in our earthquake early warning efforts we develop computer algorithms that can detect and characterize ongoing earthquakes in near real-time. Based on such estimations, sites that are about to be hit by damaging seismic waves can be warned before the onset of shaking. In particular we work on improving the accuracy of the earliest event characterizations which, in many cases, will be the only ones that are available in time, i.e. before the shaking starts.
