Abstract
This paper presents the results of rainfall restoration for Huong Hoa district, Quang Tri province from the Global Satellite Mapping of Precipitation (GSMaP), calibrated with rain monitoring stations for the period from year 2000 ÷ 2022 by Quantile Mapping method. The results show that the correlation of rainfall after adjustment increases on average by 11%, some stations up to 25%. Rainfall recovery results are used as input to calculate landslide hazard for some communes in Huong Hoa district, Quang Tri province.
