Nepal lies in the southern slopes of the Himalayan
range, which is one of the most active mountain ranges in the world. The
Himalayan range was formed due to collisions between the Indian and Tibetan
plates. As a result, there is a presence of active faults that pose constant
threats of the earthquake in the country. Nepal has a long history of
destructive earthquakes each occurring in 100 years interval. The latest hit
was on August 20, 1988, which devastated the entire Eastern region and part of
the Central regions. It was 6.5 magnitude in Richter scale. It claimed 721
human lives, injured 6,553 people and damaged other developmental
infrastructures (Nepal Disaster Report 2011). Earthquake risk and vulnerability
assessment are primarily based on two things: location and magnitude of
earthquakes, and pattern of human settlement and building types. So far, we
have good understanding about the active seismic zones but we cannot accurately
predict the magnitude and time of the earthquake. Hence, to minimize the
earthquake risk, we need to reduce the social vulnerability related with human
settlement and building types. This work aims to understand how the human
settlement has been increased in one of the eastern city of Nepal, Dharan,
using Landsat sequential images and are exposed to constant threat of
earthquake risk.
