A 3.8 magnitude earthquake occurred in the mountainous areas of Gangwon, North Korea.
The Korean Meteorological Administration said on the 11th, “A 3.8 magnitude earthquake occurred at a depth of 16㎞ to 32㎞ northwest of Pyeonggang, Gangwon, North Korea at 7:45 pm”, and “the maximum intensity II reach Gangwon, Gyeonggi, Seoul and Incheon. ” .
Jindo II is a quiet state or smoothie that can only be felt by a small number of people above. According to the Korean Meteorological Administration, as of 8:00 p.m., a total of 39 complaints (reports of earthquake sensation) were received in the metropolitan area and Gangwon-do, including 4 in Seoul, 31 in Gyeonggi and 4 in Gangwon, starting at 8:00 pm
“We regret reporting in Gyeonggi, Seoul and Gangwon, but they are mostly silent,” said Ki-Han Yoon, secretary of the Korea Meteorological Administration.

The Meteorological Administration said: “This earthquake is analyzed as a natural earthquake.” “The upper and lower vibration width (S wave) of the seismic wave is greater than the left and right vibration wave (P wave),” Yoon said.
The place where the earthquake occurred is within the latitude of 38.68 latitude and 127.18 longitude of 2.5 km. This is the sixth earthquake with a magnitude of 2.0 or greater that occurred in a location similar to the location of the earthquake, beginning with an earthquake of 2.4 on August 28, 2016. The scale has increased slightly from 2.4 to 2.6 to 2.3 to 2.9 to 3.5 to 3.8.
The most recent earthquake on September 21 of last year exceeded 3.0 for the first time. This earthquake occurred at a point of 1㎞ radius and 17㎞ depth, registering a scale of 3.5 and a maximum magnitude of Ⅱ. It is almost the same type as the 11th earthquake.
It occurs next to two faults.
The Korean Meteorological Administration analyzed the cause of the earthquake in September as a “floating movement.” Analyst Woo Nam-cheol of the Korea Meteorological Administration said: “It is very likely that the earthquake occurred in almost the same location as the September earthquake last year.” It is a common type of earthquake. ”
According to the Korea Meteorological Administration, the area where this earthquake occurred is an earthquake-prone area where there have been 18 earthquakes 2.0 or more in radius of 50 km since 1978. Analyst Woo said: “We will analyze this fault in detail and we will release it soon. ”
