After 4 minutes, there was a larger aftershock with a magnitude of 6.2 M. The earthquake that hit Nagari Malampah, Pasaman District and Nagari Kajai, Pasaman Barat District, which caused a number of people to die and minor, moderate to severe damage to people’s houses. Based on the large number of houses damaged, it is necessary to assess the vulnerability of buildings in Nagari Kajai. The vulnerability assessment was obtained from the results of building evaluations where the results of building vulnerability were in the moderate vulnerability category 47 houses and 53 houses with high vulnerability. Most of the vulnerability occurred due to community buildings that were not built according to building standards therefore it was necessary to educate the public on how to repair houses that meet house standards. This paper provides one solution to the community whose houses were damaged through community service activities which the Team carried out with training activities for retrofitting community houses that were moderately or lightly damaged and provided examples. Retrofitting houses is highly expected by the community.
