给出了1900-1970年印度东北部和缅甸的地震活动图。在缅甸平原的下面发现了一个中等深度的震源区，该震源区倾向于Arakan Yoma的东部。地震带呈V形。确定了缅甸地震的六个新的震源机制解。这些机制与Fitch（1970）、Rastogi等人（1973）和Tandon和Srivastava（1975）的早期研究相结合，表明缅甸既有逆冲断层，也有正断层。压应力轴被发现是更接近垂直比水平。根据应用于印缅地区的板块构造理论，对结果进行了讨论。
A seismicity map of northeast India and Burma for the period 1900–1970 is given. A zone of intermediate-depth foci dipping to the east of Arakan Yoma is found to be present underneath the Burmese plains. The seismic zone appears to be of V shape. Six new focal-mechanism solutions of earthquakes in Burma have been determined. These mechanisms, in conjunction with earlier studies of Fitch (1970), Rastogi et al. (1973) and Tandon and Srivastava (1975), indicate that normal as well as thrust faulting takes place in Burma. The compressive stress axis is found to be more nearly vertical than horizontal. The results are discussed in the light of plate-tectonic theory as applied to the Indo-Burma regions.
