... extensively exposed in the massif. Constraints on the extent of the source area provided by bedrock cooling ages together with sediment-flux estimates at Pasighat, India, suggest exhumation rates averaging 7–21 mm yr −1 in an area of ~3300 km 2 centered on the massif. This rapid exhumation, which...

Model results related to 1697 CE. The Sadiya earthquake of a magnitude of 7.9 ± 0.2. Surface rupture information from palaeoseismological studies: Him: Himebasti, Nig: Niglok, sites with no observed seventeenth-century surface rupture, according to Kumar et al. (2010) and Priyanka (2019). Na: Nameri, Har: Harmutty, and Pa: Pasighat. Intensity observations are described in the text: Sa: Sadiya; Ba: Barnadi Bridge. Possible loci of hypocenters, as constrained here, are shown for the M7.7 and M8.1 scenarios (purple contour). The red star and blue circle, respectively, indicate the location of the 1950 Tibet-Assam earthquake and its aftershocks of Mw>6, HFT: Himalayan Frontal Thrust; MT: Mishmi thrust; NT: Naga Thrust and MA: Manabhum Anticline.
