by Stephen Angster, Eric Fielding, Steven Wesnousky, Ian Pierce, Deepak Chamlagain, Dipendra Gautam, Bishal Nath Upreti, Yasuhiro Kumahara, and Takashi Nakata

This supplemental material includes color versions of Figures 3 and 4 in the main article (Figures S1 and S2). Figures S3–S28 are additional photographs of the Kausaltar fracture sets indexed to Figure 4a in the main article (reproduced here as Figure S2); the number in the upper left corner of each photograph gives the location number indexed to this map. Figure S28 shows a small-scale map of factories with brick chimneys distributed throughout Nepal and northern India.

Figures

Figure S1. Color version of Figure 3 from main article showing color hillshade image of Kathmandu Valley developed from 8 m DEM (Noh et al., 2015). Large solid orange dots indicate sites traversed locally and where local inhabitants were queried. Previously mapped faults are shown as thick black lines, and newly defined lineaments are shown as thin black lines. Inset corner figures are enlarged views of the indicated areas displaying chimney data collected at (a) East, (b) West, and (c) South Kathmandu sites. (d) Displays chimney data from the Indo-Gangetic Plain (see Fig. 1 of the main article for location); white arrows show the fall direction from the mainshock, and the black arrow in (b) shows the fall direction resulting from the large aftershock.

Figure S2. Color version of Figure 4 from the main article. (a) Map of the northeast-trending Kausaltar fracture set. Red barbells show the downthrown side of the fracture. Yellow dots show locations of the associated photos in this electronic supplement (Figs. S3–S27). (b) Same-scale map as in (a), showing the fractures and field measurements underlain by a colored hillshade image (Noh et al., 2015). Contours mark 5 m intervals.
