|
| EMS
Intensities in this table have been assigned by Roger Bilham and Ellen Knappe
based on site visits or low-level helicopter overflights [6.5 signifies intensity 6 to 7]. |
| Locations
are assigned precise coordinates, but are named after the nearest
identifiable town, sometimes >1 km distant. |
| Although
the linked photographs are typical of epicentral damage the estimated EMS
values are often based on numerous additional observations. |
| In
some cases the assigned intensities have been influenced by interviews or
videos, walk-throughs, and/or evaluations of mortar quality and steel
ductility. |
| Narrative
pdf descriptions are linked to some study areas- e.g. a search for surface
rupture, the Barpak region, Thulo Sabro, the Langtang region and the Kathmandu Valley |
