Although the data might appear to be biased and shows that the Asian countries are more sympathetic towards Nepal, but this does not takes into fact that out of 10,000 tweets mined, only ~300 had latitude and longitude values( only 205 had non zero values). And there’s a pretty good possibility that most of the tweets from western countries have no geographical information, because of privacy.
