A prior-informed integrated particle filter (πIPF) method for earthquake early warning using ETAS model

Abstract Earthquake Early Warning (EEW) systems often have difficulty estimating the source location in the first seconds after detection, especially for events in islands and peninsulas where station coverage is sparse and azimuthal geometry is biased. To address this limitation, we develop a prior...
