The largest earthquake is the 6.2 earthquake (8km from the epicenter) that occurred in Jishishan County, Linxia Prefecture, Gansu Province on December 18, 2023.

According to CCTV news, the reporter learned from the Qinghai Provincial Emergency Department that, as of 20:56 on December 20, the Gansu Jishishan 6.2 earthquake had killed 22 people, injured 198 people and lost contact with 12 people in Haidong City, Qinghai Province. At present, the search and rescue work for the lost persons is still in tense progress. In addition, as of the 20th, 113 people had been killed and 782 injured in Gansu.

At present, the Jishishan 6.2 earthquake has killed 135 people.

Qinghai "Shachong" rescue site: more than 600 rescuers search non-stop

According to CCTV News, due to the 6.2 magnitude Jishishan earthquake, a rare geological disaster occurred in Hexian County, Haidong County, Qinghai Province. The earthquake triggered "sand surge", which caused sand liquefaction. A large amount of soil poured into two villages, washed down some houses, and caused casualties and missing people. At present, 13 people are still out of touch.

It is worth noting that the number of lost contacts is gradually decreasing, while the number of victims is rising. It is understood that after two days of intensive rescue, rescue workers have found the remains of seven victims.

After the earthquake, because some people could not get in touch, the rescuers worked closely with the local people and, under the guidance of their families, roughly determined the location of the missing people through manual search, search and rescue dogs, life detectors and other means. At present, the rescue force is mainly concentrated in 5 points for continuous search and rescue.

According to the CCTV reporter, after the emergence of "Shayong", it presents a very viscous, high water content and tight texture soil structure. As many search and rescue sites are surrounded by a large amount of mud, personnel can only reduce the pressure by erecting boards or laying linoleum, and barely reach the rescue site.

However, it is impossible for large machinery to enter at all, because it is observed that the average thickness of sludge is about 2 to 3 meters. Therefore, the rescue personnel take the manpower first approach, and the manpower first carries out the search and dredging rescue. Where large machinery cannot reach, the primary task of many large machinery is to remove the sludge on the road leading to the rescue site.

Due to the unstable state of "sand surge", it will melt and become very thin and soft when the rising temperature of the sun rises in the daytime. It is often difficult to excavate because the surrounding "sand surge" will be backfilled quickly soon after excavation by excavator. Similarly, when the water content is high at night and the temperature drops below 0 ℃, the "sand surge" will freeze and have a certain impact on the excavation.

Since the excavator could not reach some rescue sites in time, it had to rely on manpower for excavation. The fire rescue personnel shall adopt the shift system, take a break every 2 hours, and carry out search and rescue uninterruptedly.

The largest resettlement site in Jishishan County, Gansu Province: from 900 to 1600

Dahe Village, the largest resettlement site in Jishishan County, Gansu Province, has witnessed the biggest change with more tents and more people. From 100 tents on the evening of 19th to 170 tents on the 20th. The number of displaced people increased from more than 900 to 1600. The increase of so many personnel undoubtedly brings no small challenge to the security work.

① The guarantee of power and communication has been further upgraded. On the 19th, about one-third of the tents were electrified. Now, all tents have been electrified. Through the light from the tent, the whole settlement area is full of warmth. The increase of personnel has brought great pressure to communication. In fact, the communication in the whole disaster area has recovered to the level before the earthquake. However, for places where people are particularly concentrated, such as centralized settlements, communication still faces considerable difficulties. Several operators have added temporary base stations to provide signal enhancement services.

② Some details in the tent are adjusted. On the 19th, the whole tent was about "three cotton and one warm": cotton tent, quilt, cotton mat and a stove (some have stoves). On the 20th, all tents were equipped with stoves, and some electric mattresses were distributed in succession. Of course, these facilities are matched by the increase of firefighters and readiness, from 30 to 60.

③ Meal changes. Previously, a large number of instant noodles and some stewed dishes brought by PLA officers and soldiers were also provided. Now, there are also dumplings, beef noodles and other delicacies provided by some caring people.

④ The change of everyone's mood. Compared with the 19th, we may be more stable and active.
