Role of the Kopili Fault in Deformation Tectonics of the Indo‐Burmese Arc Inferred from the Rupture Process of the 3 January 2016M_w 6.7 Imphal Earthquake

Distribution of b‐values in Indo‐Burma Ranges, northeast India: Implications to structural heterogeneities and style of faulting

“…Meanwhile, the August 6, 1988 earthquake of M W 7.2 was a major earthquake, which occurred in the IBR region at 99.0 km focal depth. Recently, an earthquake of M W 6.7 occurred in the IBR on January 3, 2016, having its origin in and around 40 km north‐west of the centre of Imphal (IMP) as shown in Figure 1 with a focal depth of 59 km (Borgohain et al, 2018; Gahalaut et al, 2016; Singh et al, 2017). In the IBR, earthquakes generally occur at deeper depths ≥150 km, however, in the Sagaing fault region, occurs at shallower depths.…”

“…It is reported that the oblique plate convergences between the Indian Plate and the Asian Plate take place at an average rate of about 54 mm/year (DeMets, Gordon, Argus, & Stein, 1994). Several researchers studied the seismotectonic of the Indo‐Burma Ranges (IBR) with reference to whether subduction is still continuing, to ascertain the subduction dynamism in association with its geometrical disposition and variability in the stress pattern with the recorded seismicity in the region (Curray & Moore, 1974; Hurukawa, Tun, & Shibazaki, 2012; Kayal, 1998; Kundu & Gahalaut, 2012, 2013; Satyabala, 2003; Singh, Rao, Kumar, Hsieh, & Zhao, 2017). The oblique convergence of the Indian Plate has produced the creation of a sliver plate between the subduction zone and the Sagaing Fault in the north, the right‐lateral Sumatra and Java fault systems in the south, and unlocked the Andaman Sea Ridge in the Andaman Sea (Curray, 2005).…”

“…Subsequently, the subduction terminated by slow sinking of the overturned slab leading to its detachment manifested as reverse faulting mechanism. However, based on the waveform modeling it has been argued that the deformation in Burmese arc is mostly accommodated by northward slivering of the eastward subducted Indian lithosphere (Singh A. P. et al, 2017). Significant work has been done with imaging of the detail lithospheric architecture of the subducting slab using stat-of-the-art tool, S-to-p receiver functions (Uma et al, 2011).…”

Regional variation of coda Q in Kopili fault zone of northeast India and its implications

“…It's length is roughly 300km and width is 50km. Very recently [22] cited about the role of Kopili fault in the recent Imphal earthquake. Furthermore, [1] estimates the body wave attenuation mechanism for this study area using direct P and S-wave.…”
