Meizoseismal regions and dates of large to great historical earthquakes outlined by bordered white lines, specifically, the 1905 Kangra, 1934 Bihar-Nepal, 1897 and 1950 Assam earthquakes.

Supplemental Figure 4. Map of fluvial terrace deposits (black) along the Markanda River. Contours of 100 m are solid and intervening 20 m contours dashed. Inset shows typical character of strath terrace deposit resting unconformably over dipping beds of Siwaliks Group. The strath deposits are typically composed of rounded pebble-cobble gravels capped by a fine-grained loamy sand unit. Map locations and context of dendrochronologically corrected ages of samples MT-001/5 and MT-001/3 are shown in map and inset, respectively. Heavy black line shows the location of radiocarbon samples in map view and in exposure section.
