This study has provided materials and curricula for disaster education in China and Japan. Most students show improved results. The ability of students to utilize electronic devices affects the learning of GIS-related content rather than other aspects. The frequency of daily usage of online maps and daily attention to disaster prevention affects learning the entire materials. This study can better understand the benefits and limitations of electronic maps in disaster education.
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.
