Why were the two earthquakes not publicly announced in the early morning of August 13th? Ningxia Earthquake Bureau Response Website | Earthquake. But by the Seismological Bureau
On the early morning of August 13th, earthquakes of 1.1 and 1.4 magnitudes occurred in Yinchuan City. Due to the amplification effect of the soil layer in the Yinchuan sedimentary plain, and the fact that two small earthquakes occurred in the early morning, the environment was relatively quiet, causing some people to feel it.
A large number of earthquake practices have shown that earthquakes below 3.0 have little impact on the public, and many people often do not feel it. Therefore, in order to reduce information interference to the public and improve the efficiency of earthquake information dissemination, our bureau will not publicly release earthquake information below 3.0 levels to the public, and the relevant data will only be used for internal research.
Our Weibo account usually replies to comments from netizens through private chat, and has also received recognition from the commenting netizens. But because it was a private chat reply, it was not displayed on the webpage. Thank you to the netizens for their concern and support in earthquake work. Our bureau will humbly accept the opinions of netizens, accept supervision from all sectors of society, and strive to take measures to respond to the public's concerns.
