The area of Mongton is located in the central part of main stream of Salween. There has a straight-line distance of 200 km to the border of China’s Yunnan Province and 90 km to the border of Chiang Mai Province of Thailand. There are two earthquake concentrating regions of destructive earthquakes within this area. It reflects the collision between the Indian plate and the Eurasian plate. The main regional seismic activity characteristics are summarized as follows in accordance with the spatial-temporal distribution characteristics of the seismic activity and the estimated future seismic trend of the area under analysis: (1) There are 132 times of destructive earthquake occurrences of M ≥ 4.7 that occurred ever since the record within this area. There are 2915 modern small earthquakes of 4.6 ≥ M ≥ 2.0 being recorded within this area totally since 1966. (2) Orientation of axis P of the maximum principal compressive stress of the regional focal mechanism solutions is mainly distributed in the angular domain in the direction of NNE–NE–NEE and under the horizontal action, which indicates that the distribution of the tectonic stress fields within the area is very complicated with the spreading of the earthquake fracture planes displaying a characteristic multi-directionality. (3) This area is located at the intersection of the Himalayan Seismic Belt and the Southwestern Yunnan Seismic Belt; the seismic activities involved display an obvious alternate quiescence and active phenomenon. It will experience a strong seismic activity level similar to that of the previous 100 years in the future 100 years. Large earthquakes are likely to occur within this area.
