1. Overview<\/strong>
We monitored a residential area on steep terrain in Hokkaido, Japan, using ground-based SAR for more than two years. The observations captured the movement of a house affected by a retaining wall failure, including acceleration preceding its collapse.<\/p>\n\n\n\n

2. Technology Developed<\/strong>
We established a processing workflow to track small displacements at five-minute intervals and proposed an early warning framework based on movement acceleration. Retrospective analysis estimated the collapse time approximately 30 minutes earlier than the actual event.<\/p>\n\n\n\n

3. Potential Contributions<\/strong>
Remote monitoring of houses and slopes can help assess the risk of further failures after a disaster and support decisions on evacuation and safety measures.<\/p>\n\n\n\n

4. Future Outlook<\/strong>
We will address the effects of snow cover and thermal expansion, validate the approach at additional sites, and work toward an operational real-time early warning system.<\/p>\n\n\n\n
