China Meteorological Administration raises its emergency response level for earthquake disaster meteorological services to level two
At 9:05 Beijing time on January 7th, a magnitude 6.8 earthquake struck Dingri County, Xigaze City, Tibet, causing significant casualties and a large number of collapsed houses. After comprehensive research, the China Meteorological Administration upgraded the meteorological service emergency response for earthquake disaster from level three to level two at 15:00 on the 7th, and the Tibet Autonomous Region Meteorological Bureau adjusted the corresponding emergency response status based on actual research.
The true color image from Fengyun 4B satellite at 11:30 showed that the earthquake zone (marked in red) was cloudless.

In addition, analysis of pre-earthquake high-resolution satellite images with a resolution of 16 meters (Figure 2), land use maps (Figure 3), and thematic maps of topography (Figure 4) showed that the epicenter of the earthquake was located in an area of water bodies, and the surrounding area was primarily grassland. Meanwhile, pre-earthquake high-resolution satellite images with a resolution of 2.5 meters (Figure 5) revealed detailed surface information in the earthquake zone.

Weather forecasts indicate that for the next three days (January 7th to 9th), Dingri County will be mainly sunny, with a lowest temperature range of -18℃ to -14℃ and a highest temperature range of 0℃ to 7℃.
The temperature in the recent earthquake zone is low, and people may feel cold. The ultraviolet radiation is strong, so disaster relief personnel should take measures to keep warm and prevent hypothermia. When using emergency tents for取暖, attention should be paid to safety, and precautions should be taken to prevent carbon monoxide poisoning when using open flames.
