Quozawa: in principle, i've always believed that since rain can forecast, earthquakes should also forecast. But in reality, there is no reliable method of universal application. There are no forecasts for the wenchuan earthquake, the jade earthquake and this earthquake. If an earthquake can forecast, why doesn't the department forecast? The seismic bureau will not be so irresponsible, mainly because of its inability to shoulder that responsibility. In particular, these earthquakes occurred in very few locations. Some of the sites are more numerous and may capture some of the previously discovered pre-earthquake phenomena, giving some kind of seismic prediction, as in the case of the sea city earthquake。
