Abstract
This study clarifies the actual situation of data linkage in municipalities during disaster
response, based on the case of Wajima City, Ishikawa Prefecture, during the Noto Peninsula
Earthquake of 2024. GIS was utilized as the information infrastructure for data processing and
visualization. External support groups and the affected municipality utilized a common
infrastructure, enabling not only efficient on-site collection of information and simple tabulation,
but also the creation of analytical data. As a result, it was suggested that information necessary
for operations could be substituted by other information. The created data was compiled and
utilized according to the purpose of sharing, decision making, and progress management.
