Abstract: The huge destruction of the earthquake of 7.6 and 6.2 MW in Padang, West Sumatra, Indonesia on September 30, 2009 caused widespread death of more than 1,200 people and destruction to the heavily populated and relatively prosperous region. In this paper a summary of earthquake effects to structural damage on road infrastructure and geofailures, i.e., landslide and debris flow, during the earthquake were identified based on direct field observation at several districts, i.e. the city of Padang, Padang Pariaman, Pariaman and Agam. The levels of earthquake damage were classified from low to severe destruction level for road pavement and bridges. The earthquake also caused events of landslides and debris flows close to road networks which killed hundreds of people while hundred kilometers of road pavement were made inaccessible. Some road networks were totally collapsed and as a result, several villages became isolated areas.
