Abstract
The rapid urban development of Musikot from a small bazaar settlement to a mid-size trade and service centre in
rural Nepal increases the vulnerability of its inhabitants to natural hazards. Population growth and improved road accessibility
has led to increased construction and an expansion and alteration of the built environment. The growing availability of modern
construction materials like concrete and steel allows for new architectural designs and the erection of additional storeys on
existing buildings, which contributes to the instability of the building stock. The aftermath of the April 2015 Gorkha Earthquake
demonstrates the severe consequences of such haphazard construction practices in seismically active locations. A lack of
implementation and enforcement of regulatory frameworks for building construction and spatial planning raises the risks for
the local population. Taking Musikot as a characteristic case study of rapid urban change, this article analyses it’s increasing local
earthquake-risk in light of insufficient seismic building code implementation and risk-sensitive urban planning. Applying an
approach that combines repeat photography and field mapping, the urban development of Musikot and the increasing fragility
of the building stock are assessed using a modified seismic evaluation scheme for local building types. Almost one fourth of
all construction was found to be at high risk of damage to earthquakes. It is argued, that without proper training in earthquake
resistant construction techniques and awareness campaigns, the (mal-)adoption of modern construction materials will amplify
earthquake risk in rural centres. This study stresses the need to broaden the research of disaster risk reduction and adequate
adaptation strategies beyond the current focus on large agglomerations to include rapidly urbanising small settlements in rural
areas, which are all too often neglected.
