Is Mudanjiang City in an earthquake zone?

First of all, Mudanjiang is indeed in an earthquake zone, and earthquakes should occur frequently. But the earth's crust in the Mudanjiang area is very thick, and the earthquake sources are deep, so we can't feel any earthquakes at all. Therefore, no matter who predicts when there will be an earthquake in Mudanjiang, don’t take it too seriously, because Mudanjiang is indeed a good Feng Shui land.

Background

my country is located in the southeastern part of the Eurasian plate. The geological structure is complex. It is squeezed by the Pacific Plate and the Indian Ocean Plate. Seismic fault zones are well developed and the seismic activity range is wide. High intensity and high frequency. Earthquakes, in short, are ground shaking, but the complete explanation should refer to the phenomenon that energy waves excited somewhere inside the earth quickly release energy due to obstruction when they propagate upward to the ground, causing the ground to vibrate, shake, or crack. In other words, an earthquake generation process consists of three stages: energy excitation, energy propagation and energy release. Earthquake precursors that can be directly detected by human senses are called macro-precursors of earthquakes, or macro-precursors for short. The more common ones include abnormal water level and water quality, abnormal habits of animals and plants, abnormal electromagnetic fields, etc. Abnormal changes in groundwater such as well water before the earthquake mainly manifested as sudden rise and fall of the water surface, changes in color and taste, bubbling, temperature rise and fall, sudden changes in spring water flow, and sudden changes in hot spring water temperature.
