Spatial analysis of damage due to the eruption of Mount Kelud in February 2014: lessons learned for better regional planning

Abstract

The eruption of Mount Kelud in February 2014 released eruptive material that caused lava flooding from the sub-watershed. Lava floods cause land-use changes, land damage, and infrastructure damage. Ngantang Sub-district Malang Regency is the area most severely affected by the eruption of Mount Kelud. This paper aims as a preventive effort to reduce disaster risk through spatial evaluation of vulnerability due to lahar sediments and directives for infrastructure and settlement planning in volcanic areas. Using scoring and map overlay techniques for vulnerability analysis and planning directions. The findings highlight that villages along the river have a higher level of vulnerability and disaster risk and are not recommended to build and use land within a 100 meters radius of the river wall for various community activities. Another finding is the lack of strong indicators of disaster risk reduction capacity in Ngantang Sub-district. This phenomenon proves that there are still many challenges to realizing disaster risk reduction as mandated in Law No. 24 of 2007 and Regulation of the Head of BNPB No. 2 of 2012.
