According to reports, the earthquake has caused 43.26 kilometers of road damage and economic losses of 860,000 yuan; Five bridges were damaged, with an economic loss of 2.5 million yuan; The road collapsed by 3 1, and the economic loss was 365,438+10,000 yuan; The mountain collapsed by 265,438+10,000 square meters, and the economic loss was 265,438+10,000 yuan; Ditch collapse and damage 15 16 km, economic loss of 4.5 million yuan; The water supply pipeline was damaged by 25 kilometers and the economic loss was 2.5 million yuan. According to incomplete statistics, the 8.03 earthquake caused economic losses of 460.26 million yuan.
In addition, the earthquake also caused 1.55 million people in Weining Yi, Hui and Miao Autonomous County, Bijie City, Guizhou Province to be affected, more than 7,200 people were urgently relocated, more than 700 houses per kloc-0/.55 million were seriously damaged, and more than 7,000 houses of more than 2,800 households were generally damaged. Ningnan county, Jinyang County, Liangshan Yi Autonomous Prefecture, Sichuan Province 1.65, 4.38+0.6 million people were affected, nearly 500 houses in 100 households were seriously damaged, and more than 2,000 houses in 400 households were generally damaged.

The specific casualties need further verification.
The basic characteristics of this earthquake are large magnitude, shallow source, dense population in the disaster area and poor seismic performance of houses in the disaster area. This earthquake is the first earthquake of magnitude 6.5 or above after the Yao 'an earthquake in Yunnan on June 65438+1October 65438+May 6, 2000. The focal depth of this earthquake is only 12km, which belongs to shallow earthquakes. At the same time, the disaster area is densely populated, reaching 265 people per square kilometer. Based on the above characteristics, it is estimated that the loss of this earthquake disaster will be very serious.
The earthquake caused 4 1 local base stations to stop, accounting for 1 1.2% of the total number of base stations in the county, and the telephone traffic increased to some extent after the earthquake. However, the earthquake did not seriously affect the local communication, and the communication network in the earthquake area operated normally, and there was no total communication resistance between the local network and the county and township levels.
By 20: 00 on August 3, 20 14, according to the report of Ludian county people's government, by 20: 00, the disaster had caused more than 2000 houses to collapse and damaged more than 30000 houses, and the traffic, electricity and communication in the disaster area were completely interrupted. 20 14 On August 3rd, Yunnan Ludian earthquake with magnitude of 6.5 has caused the formation of a dammed lake in Hongshiyan area of Lehong Township.
On August 3rd, 20 14, according to the report of Ludian Earthquake Administration, Niulan River in jiangbiancun area of Zhichang Township was blocked by the earthquake, and the lives and property of more than 800 local villagers were threatened. The water level of the dammed lake blocked by Niulan River is rising continuously and rapidly, rising by about 1 meter per hour. Twenty farmhouses were flooded and 19 houses were flooded. Dangerous situation handling, mass transfer and emergency rescue and disaster relief work are under intense progress.
20 14 On August 4th, the earthquake in Ludian, Yunnan Province led to the formation of a dammed lake in Qujing City, and the water level of the river continued to rise, rising at the rate of 1 m per hour. Now 20 farmers' houses are flooded, and 19 houses are flooded.
20 14 On August 4th, Yunnan Ludian earthquake caused the dam at the intake of Hongshiyan Power Station in Niulan, Jiang Huo to collapse, forming a dammed lake. More than 40 flooded families and more than 200 people in the reservoir area have moved, and people in areas threatened by the dammed lake are urgently moving.
On August 5, 20 14, the water level of the dammed lake has tripled.
On August 5, 20 14, at 15, the 8750 Armed Police Force received an order to transport and drop 200 kilograms of explosives in the dammed lake, and planned to carry out blasting on the morning of the 6th. After receiving the order, the Ministry quickly selected 25 party member commandos to undertake this task. After the Armed Police Traffic Force opened a road, the officers and men went down to the lake with a 50-meter-long cable and set foot on the levee of the dammed lake.
20 14 At about 20: 00 pm on August 5, officers and men placed explosives around the dammed lake by assault boat, ready to return along the original road. However, due to the continuous landslide, the road was blocked again and the cable could not be used. The officers and men could not return along the original road, so they had to find an open space to wait for rescue. Because the sky is dark and there is a danger of landslide, the rescue forces are temporarily unable to carry out rescue and can only wait until dawn to carry out rescue. Twenty-five officers and men found an open space near the dammed lake waiting for rescue.
On August 12, 2065438, the China Armed Police Hydropower Unit, which was rescued in Ludian disaster area, revealed that after five days and nights of fighting, an spillway with a length of 753 meters, a top width of 30 meters, a bottom width of 5 meters and a depth of 8 meters successfully penetrated the dam body of Niulanjiang dammed lake on August 12 15: 30.
It is estimated that in the next three days (August 4-6, 20 14), there will be obvious rainfall in Ludian earthquake area, accompanied by lightning, including moderate to heavy rain from the night of the 4th to the 5th.
On August 4th, 20 14, Chen Qinghao, a meteorologist from Voice of China and China Meteorological Bureau, introduced that there will be a lot of rainfall and lightning in the earthquake zone in the next ten days (August 4th to June 5438+04, 20 14), which is unfavorable to transportation and disaster relief. We should do a good job in rain protection, lightning protection and lightning protection, and focus on preventing geological disasters such as landslides, mudslides and collapses that may be induced by earthquake aftershocks. In addition, rainfall will also do harm to the safety of the dammed lake, so it is necessary to do a good job of monitoring and evacuation.
According to the latest weather forecast of the Central Meteorological Observatory, in the next three days (August 7-9, 20 14), there will be cloudy showers or thunderstorms in the Ludian earthquake zone in Yunnan, with light rain as the main rainfall and moderate to heavy rain in some areas. On August 7th, 20 14, any Tsinghua, deputy director of the Center for Disease Control and Prevention of the National Health Planning Commission, said that the earthquake-stricken area in Ludian, Yunnan Province was a high-incidence area of tuberculosis, and the earthquake caused the human body's ability to decline, and crowded people in tents might lead to clustered cases of tuberculosis. In addition, respiratory infectious diseases and drinking water problems may also be severely challenged by the next step of disease prevention and control.
In view of the high temperature of nearly 30 degrees at noon in the earthquake-stricken area of Ludian, Yunnan, the medical service team of Yunnan Public Security Frontier Corps is cooking large pots of medicines for the people in the disaster area to prevent heatstroke and cool down. This medical team consists of 50 medical staff, most of whom have participated in disaster relief in Wenchuan, Yushu, Zhouqu and Yingjiang, and have rich experience in post-earthquake rescue.
