Research and Analysis on the DPRK Leadership
The US Geological Survey received “Did You Feel It?” reports from the DPRK, PRC and Japan about the artificial earthquake caused by its fifth nuclear test on September 9.
The location is a general location of the person reporting. There are four that are directly in the DPRK. The MMI is the intensity at which they felt it and the color is a visual intensity rating, red being the highest and white being the lowest. The responses is how many responses were received per location. The distance is the distance they are from the origin of the earthquake, in this case, explosion. The last two columns are the geo-coordinates of their location.
