Real-time magnitude proxies for earthquake early warning in Israel

In quest for robust real-time magnitude proxies for earthquake early warning (EEW) in Israel, we use off-line data from 95 earthquakes of magnitudes 2.5–5.3 that were recorded by 25 stations of the Israel Seismic Network between 2003 and 2011. We first examine correlations between the catalogue magnitudes and five different attributes of the early part of the P phase, including the low-pass-filter...
