Exploring the feasibility of on-site earthquake early warning using close-in records of the 2007 Noto Hanto earthquake
Earth, Planets and Space volume 60, pages 155–160 (2008)
In view of the remarkable success of the Japan Meteorological Agency earthquake early warning system (developed jointly with the National Research Institute for Earth Science and Disaster Prevention) during the 2007 Noto Hanto earthquake, we explore the use of an on-site early warning method with the hope of eventually enhancing the existing system for more robust and faster warning. We determined two early warning parameters τ c and Pd using the K-NET and KiK-net data for the 2007 Noto Hanto earthquake as well as 20 large earthquakes in Japan. An extended method suggests a possibility of using the initial displacement amplitude data for faster warning. For the two nearby sites at the epicentral distances of 7 and 19 km of the 2007 Noto Hanto earthquake, an early warning can be ideally issued at 2.27 and 5.46 s, respectively, before the peak ground motion velocity occurs at the site.
