A strong shaking judgment method and device can use earthquake data recorded at all places in the world to process strong shaking waveform analysis in order to attain strong shaking characteristic parameters. These parameters are used as judgment standards of a strong shaking. A strong shaking judgment method according to the invention is described as follows: first, calculate and analyze every kind of earthquake characteristic parameter, such as a maximum acceleration value, number of times for passing over acceleration threshold, maximum velocity, maximum displacement, shaking energy index and shaking frequency, from acceleration change in a certain preset time frame. Next, use these six parameters to process a strong shaking judgment. A strong shaking judgment device can use a battery module, acceleration sensor module, micro controller module, alarm output module and state display module. The device in coordination with the method mentioned above can process a strong shaking judgment.
