The characteristics of stricken area (by earthquake): 1. large city 2. the city is in developing country, 3. has a relatively modern city centre, 4. has large areas of high density, 5. Has Informal suburban housing on its outskirts. 6. Has several outlying towns were also affected. 7. There was no reliable digital geospatial data documenting the city's urban. 8.
