Rapid assessment of the earthquake disaster situation is a main reference for government relief decision-making

and the rapid assessment of intensity is the base.This paper puts forward a rapid assessment system for post-earthquake intensity on the basis of ArcGIS secondary development

and introduces its function with Fuzhou basin as an example.Firstly

by a real-time data receiving procedure that has the cross-platform running ability

seismic data files recorded by the Fuzhou Strong Earthquake Networks can be imported into the system.Considering the different ground amplification factors of Fuzhou

the data files will be rapidly processed by the calculation procedure embedded in the system

then we can get the spatial distribution map of intensity and seismic peak ground acceleration isolines in 1～2 minutes.In addition

if seismic stations don’t get strong earthquake records

the system can also assess the earthquake intensity quickly according to the source parameters information from National Earthquake Networks Center.
