The present invention discloses a distinguishing and identification method of a natural earthquake and manual explosion, belonging to the field of earthquake source class identification. The method comprises the steps of: selecting earthquake 
source data, and converting longitudes and latitudes of a monitoring point as 
flat panel display; extracting earthquake 
source data of each monitoring 
station in the same earthquake event at the same moment, employing an interpolation 
algorithm to convert the earthquake 
source data to corresponding color pixel values and displaying the corresponding colorpixel values to corresponding 
flat panel coordinates on the 
flat panel, and obtaining a whole MIP space-
time sequence image; and continuously extracting earthquake source data of each monitoring 
station in the same earthquake event at the next moment, generating a corresponding MIP space-
time sequence image until the event is finished, and obtaining MIP space-time 
image series formed by the obtained MIP space-
time sequence images; according to the MIP space-time 
image series, extracting the change features and the average brightness of colors in the MIP space-time sequence images; and performing distinguishing and identification of the natural earthquake and the manual explosion according to the change features and the average brightness. The distinguishing and identification method of the natural earthquake and the manual explosion can perform distinguishing and identification of the natural earthquake and the manual explosion.
