Figure 4
The bar chart shows variations in donation value per person across different material categories over 28 days after the earthquake. The horizontal axis represents time in days, and the vertical axis represents value in United States dollars per person. Each bar indicates a donation type: life-sustaining materials, daily necessities, medical materials, and rescue equipment. The values peak within the first 8 days, particularly for daily necessities, reaching around 50 United States dollars per person. Subsequent days show a sharp decline, with only small contributions beyond day 16, reflecting a rapid drop in donation value over time.Daily changes in the per capita value of different relief materials (US$) after the earthquake
