Abstract: | C
v is used in this paper to describe the variation in inhomogeneity of spatial and temporal distribution of precursors. The
inhomogeneous variation in the spatial and temporal distribution of the anomalies in water radon and electromagnetic waves
before M
s≈6 earthquakes in northern North China is analyzed in detail. Results show that before a moderate to strong earthquake, the
distribution of anomalies in water radon and electromagnetic waves changes inhomogeneously, i.e., C
v increases significantly. The inhomogeneity in spatial distribution of short-to-imminent precursors increases before a strong
earthquake, which may relates to the enhancement of crustal strain field. The research will not only help us to know more
about the process of seismogeny and to improve practical earthquake prediction, but also blaze a new way to do earthquake
prediction with present precursor data.
