Earthquake early warning (EEW) systems have historically been based on traditional seismic instrumentation to provide rapid location of the earthquake source and its magnitude. Seismic-based systems currently exist in Japan (Nakamura 1989; Kanamori 2007), Mexico (Espinosa-Aranda et al. 1995), Taiwan (Wu and Kanamori 2005a, 2005b), Turkey, and Romania (Wenzel et al. 1999; Ionescu et al. 2007), and are under development in California (Allen and Kanamori 2003). Instrumentation includes broadband velocity and strong motion acceleration sensors, which measure dynamic ground motions with great accuracy (e.g., Heaton 1985...
