ROI Calculation Logic

Implementing this technology could improve damage prediction accuracy during earthquakes, optimizing recovery prioritization and resource allocation. For example, in large-scale infrastructure (railways, roads), if post-earthquake inspection and recovery time is reduced by ~10%, a scenario with $10M (AI est.) in annual recovery costs could see a $1M (AI est.) annual cost reduction ($10M × 10%). It also offers potential for mitigating lost revenue from earlier service and facility resumption.

Speed to Market
6× faster than in-house development
This technology integrates existing seismometer data with seismic motion estimation systems, significantly shortening deployment compared to greenfield development. The core logic for optimally combining observed and estimated values is patent-protected, allowing licensees to bypass theoretical validation.
