Figure 2. Cross-section showing collision of tectonic plates, including the primary plate boundary fault on which the 2015 Gorkha earthquake (labeled as magnitude 7.8) occurred. The green dashed line indicates the Moho discontinuity, the boundary between crustal and mantle rocks. Below the primary plate boundary fault, the Indian plate subducts under the Eurasian plate with a mix of seismic and aseismic deformation. Aftershocks (magnitude greater than 4) that occurred between April 25 and October 30, 2015 are denoted by circles scaled according to magnitude (McNamara et al., 2017). The Gorkha mainshock along with two moderately-sized aftershocks are labeled by magnitude and their focal mechanisms (“beach balls”). KV indicates location of Kathmandu Valley.
