Discovering research trends of urban geology based on a bibliometric analysis
Keywords:bibliometric, urban geology, environmental geology, engineering geology, urban planning
Urbanization contributes to the emerging of urban areas across the world. The importance of geology to assure sustainability has led to many research publications in urban geology. This paper aims to discover the research trends through a bibliometric analysis of articles indexed within the Scopus database from 1950 to 2018 (as of the end of July) on topics related to geology and urban. The analysis found a significant increase in publication number during 1999-2016, especially after the 2004 Indian Ocean earthquake and tsunami disaster. The next finding is related to research interest clusters: (1) engineering geological hazard investigation and risk assessment in the urban area (EGR); (2) social geology and urban sustainability (SGS); and (3) urban hydrology and water management (HGW). Research gap found issues on EGR majored in underground civil planning (geotechnics) received more attention from researchers. In contrast, the least attention is on the geology and land use planning, under the SGS issues. This study may serve as a platform for scholars to understand the current status and future directions of urban geology.
