Isn't there a precursor to this earthquake?

First, the fourth mysterious disappearance warning in Guanyin Pool within 5 hours

The Guanyin Pool with a diameter of 100 meters and a water depth of tens of meters is not used all the year round. Recently, however, the lake disappeared completely in less than 5 hours, showing black silt. When the lake disappeared, a whirlpool suddenly appeared on the water surface, accompanied by a roar. The pond has dried up to the bottom, leaving black mud at the bottom.

Second, in May 1 1 day, hundreds of thousands of toads went out in droves.

Recently, a large-scale toad migration occurred in Tanmu Village, Xin 'an Town, Mianzhu City, Sichuan Province: hundreds of thousands of toads, large and small, walked on the road near a pharmaceutical factory, and many of them were crushed to death by passing vehicles and trampled to death by pedestrians. A large number of toads make some villagers think there will be an ominous sign.

Third, the earthquake clouds are everywhere.

Maybe it's because we believe in science and get rid of superstition. Maybe years of peace have made us lose our due awareness of prevention. Nature has repeatedly reminded and warned us, but we have completely lost our ability to understand it.

At this moment, they haven't realized that a terrible natural disaster has come, and we living people have never encountered such a high-magnitude earthquake in our lives. From this moment on, the earthquake prediction institutions in the whole country and even some countries in the world quickly began to collect data and constantly revise the earthquake level.

At the time of writing, the earthquake occurred less than three hours, and there were no reports of casualties and property losses in Wenchuan, the epicenter. The reporter may still be on the plane to the disaster area. I can only pay attention to the latest news on the Internet and pray for God to bless China. Some people question why there is no earthquake prediction. As we all know, the current earthquake prediction ability can not give an early warning before every earthquake, and the technology has not reached the level that allows us to avoid this disaster. We were unprepared, and the natural disaster suddenly came. This is not a human error.

However, we may rely too much on technology. All kinds of natural omens before the earthquake may have reminded us long ago, but they were ignored by our carelessness. Ancient experience tells us that there will be some precursors before earthquakes, such as abnormal animals, abnormal groundwater and abnormal weather changes. This experience has been widely recognized and written into textbooks. So, why can't people engaged in earthquake prediction be vigilant when these strange phenomena in nature occur?

West China Daily reported in May 10 that a large-scale toad migration occurred in Tanmu Village, Xin 'an Town, Mianzhu City, Sichuan Province, and hundreds of thousands of toads took to the streets. Mianzhu is only a few tens kilometers away from Wenchuan. Mianzhu is within the earthquake center. The villagers expressed concern: "Is this phenomenon a precursor to any natural disaster?" However, Mianzhu Forestry Bureau rushed to the scene to explain that this was because a large number of young toads migrated ashore during the toad breeding season, which had nothing to do with natural disasters and would not affect people's lives and reduce mosquitoes for the local area. Old people in the village have never seen this phenomenon, but experts say it is normal, which proves that Mianzhu's ecological environment is getting better and better. The warning of Nature made these experts ignore and misinterpret it. This is even a substantial misleading.

Not only in Sichuan. On May 4th, millions of toads gathered near Liu Duo Gate in Xinlou Village, Wu Jian Town, Jiangdu City, Jiangsu Province. On May 9, tens of thousands of little toads suddenly migrated on the Dongfeng Bridge in Taizhou City, Jiangsu Province. On May 1 1, tens of thousands of little toads migrated to Zhujing Garden, Guli Town, Changshu, Jiangsu.

At 7 o'clock in the morning of April 26th, the water storage in Guanyintang Village, Baiguo Village, Enshi City, Hubei Province, with a diameter of about 100 m and a water depth of several tens of meters, all disappeared within 5 hours, and the water surface suddenly appeared a whirlpool accompanied by a roar. The villagers are expecting experts to solve the puzzle, but so far they have not heard any explanation.

There is no need for expert explanation now. The Wenchuan earthquake in May 12 may have explained it for them. But this explanation makes people want to cry, and nature once again mocks our stupidity and carelessness. When there are animal anomalies and groundwater anomalies that are highly consistent with the ancient earthquake prediction experience, no one dares to remind that this is an earthquake precursor, so everyone should be vigilant. Maybe it's because it soothes people's hearts, maybe it's because we believe in science and get rid of superstition. Maybe years of peace have made us lose our due awareness of prevention. Nature has repeatedly reminded and warned us, but we have completely lost our ability to understand it, and even suffered this catastrophic natural disaster without any awareness of prevention. Is this the limitation of science or the sorrow of our wisdom?
