Abstract: Spending more than 20 days in the Wenchuan earthquake zone, I conducted a systematic field investigation into the macro-anomaly cases occurred at the earthquake region in particular in Wenchuan, Dujiangyan, Yingxiu, Beichuan, Shifang, Mianzhu, Hanwang, Mianyang, Chengdu and other counties. This article is a summary of copious examples and instances and a series of abnormal phenomena taken place in electromagnetic field, underground fluid, geographical appearances, meteorological conditions, …etc. which are considered to be earthquake warning signs and premonitions in the seismic area. Regarding the emergence of the forewarnings of the earthquake as surely appearing phenomena, this article expresses a personal point of view about the reasons of the fail to anticipating the earthquake and maintains that the close cooperation between the experts and the mass people is an indispensable means for earthquake forecasting. Then, I suggests, firstly, to mobilize the mass people into the earthquake forecasting work and, secondly, to develop the macro-watching system for the prediction of earthquake and, finally, to promote a large education for popularizing seismic knowledge.

Key words: Wenchuan earthquake, Macro-anomalies, Earthquake prediction, Observation and prediction by the masses
