Little knowledge exists about whether students can improve their understanding of disaster risk reduction (DRR) through web geographic information system (GIS) technology and which factors affect their learning. This study has provided materials and curricula for DRR education in Chinese and Japanese high schools. The daily use of online maps and attention to disaster prevention affect the learning of all the materials. Increasing the use of online hazard maps is key to realizing social DRR.

Short summary
This research might be the first time to study the topographic changes due to strong earthquakes in region of low relief. We use high-resolution pre- and post-earthquake DEMs to detect the topographic changes caused by the Wenchuan earthquake. However, the topographic changes caused by the Chuetsu earthquake is different. Our findings might indicate that the earthquake mainly acts as roughening and driving the topographic growth in region of low relief.
