Seismicity map of the 2021 Lamjung seismic sequence (colored circles, with colors as a function of hypocentral depth) in central western Nepal. The red line corresponds to the trace of the base of the ramp according to Hubbard et al. 2016, the yellow dashed lines correspond to the modeled down-dip limits at 95% of the coupling across Nepal (Lindsey et al. 2018). The orange line corresponds to the 3500 m iso-altitude, which controls the expression of seismicity along-strike Nepal Himalayas (Bollinger et al. 2004). The blue squares correspond to the location of the Bahundanda hot springs. The green star materializes the epicenter of the Gorkha earthquake, while the green lines locates the 2-m isocontours of the Gorkha earthquake slip at depth (Grandin et al. 2015). The circles in grey locate the epicenter of the earthquakes that happened between April 2015 and May 2021. The triangles correspond to the seismic stations used in this study
