Short summary
One of the quickest means of tsunami evacuation is transfer to higher ground soon after strong and long ground shaking. Ground shaking itself is a good initiator of the evacuation from disastrous tsunami. Longer-period seismic waves are considered to be more correlated with the earthquake magnitude. We investigated the possibility of applying this to tsunami hazard alarm using single-site ground motion observation.
