Updated Historic Seismicity: Nepal, Himalayas (3 data sets)

I have added one more polygon data set to the three main data sets that include records of historic earthquake slip patches. The three data sets now include Bilham (2004), Bettinelli et al (2006), and Berryman et al. (2009). I left the Rajendran and Rajendran (2011) data set off of this map because it is a point data set and the locations do not lie within the polygons from the other studies. While this may not be evidence alone, but the city locations plotted in the Rajendran article are also plotted incorrectly.

The methods that I used to digitize these data sets involves the following:
1. step (1) I georeferenced the maps by rubbersheeting them in arcGIS (into a WGS84 lat/long coordinate system). In some cases, I could use lat/long coordinates plotted on the original maps. In other cases I used nation-state boundaries, topographic landforms, and coastal shorelines. These maps are all probably within tens of kms of being in the correct location.
2. step (2) I screen digitized the polygons as plotted in the referenced articles.

Here are the GIS data sets (in zip files)
