Abstract: On the basis of mieroseic miemodulating ratio′s concept,we defined modulating bloeks ratio. It can reflect variation of earthquake field.Taking some earthquake as sexample,we conelude that modulating bloeks ratio is amedium-term anomaly oceurredl~2Year before stronge arthquakes.Anomaly mechanies of modulating bloeks rat is related with loeal strain field coneentrated and strengthen.They can be easily modulated bysolldtide.

Key words: Modulating bloke ratio, Medium-term anomaly of seismieity, Seismicitly activity
