Did the Zhouqu Debris Flow No. 7 weather forecast predict it?
The weather forecast predicts heavy rains. Debris flows are geological disasters. There will be reminders during heavy rains that cannot be predicted.
Look at the historical records:
Before the debris flow occurred at 22:00 on August 7, there had been heavy rain for two consecutive hours. According to the meteorological department, the total rainfall in these two hours was Reaching 90 mm, breaking the historical record. Perhaps it was night time, which did not arouse the high level of alertness that people should have.
After the disaster occurred, the Ministry of Land and Resources immediately attributed the disaster to areas prone to geological disasters, including five major triggers related to the Wenchuan earthquake, which were almost impossible to monitor.
In fact, this dangerous area was included in the Gansu Province Geological Disaster Early Warning Project County and City Geological Disaster Survey Project as early as 2002, and was implemented by the China Geological Environment Monitoring Institute.
The project report was completed in March 2003. Southern Weekend learned from the authoritative authority of the Geological and Environmental Monitoring Institute that this graphic report covers 140 geological sites, including two extremely large (threatened people greater than 1,000 people) debris flow areas in Sanyan Village and Luojiayu Village. The location, scale, stability, susceptibility, and endangered objects of disaster hazard points are all clearly marked. For these extremely large geological disaster hidden danger points with a height difference of more than 1,000 meters between valleys and peaks, endangering the lives of 16,000 people, the report requires that "relevant departments must not relax their vigilance and implement funds for hazard point control projects as early as possible to prevent the occurrence of debris flows."
Even in June 2008, after the Wenchuan earthquake, a Beijing expert team visited Zhouqu and determined that there were more than 60 landslides in the county, 13 of which were serious, threatening the safety of downstream villages. Must pay close attention to.
However, disaster struck two years later.
