Abstract
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 tau-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.
