Abstract

With the 3,700 New SI sensors installed throughout its service area (3,100 km2), Tokyo Gas has started to develop its super high-density real-time disaster mitigation system "SUPREME" for gas supply systems. Immediately after an earthquake, seismic data from the New SI sensors is relayed to the main system where extremely precise estimates of the damage are made on the spot. Damage estimation consists of making an estimate of the surface distribution of seismic motion that takes account of the site amplification factor, and making an estimate of damage to the pipeline network that takes account of factors such as the types of the pipes, the topography of the area, and the liquefaction conditions.

Development of Supreme Super High-Density Realtime Disaster Mitigation System for Gas Supply System

San Diego, California

With the 3,700 New SI sensors installed throughout its service area (3,100 km2), Tokyo Gas has started to develop its super high-density real-time disaster mitigation system "SUPREME" for gas supply systems. Immediately after an earthquake, seismic data from the New SI sensors is relayed to the main system where extremely precise estimates of the damage are made on the spot. Damage estimation consists of making an estimate of the surface distribution of seismic motion that takes account of the site amplification factor, and making an estimate of damage to the pipeline network that takes account of factors such as the types of the pipes, the topography of the area, and the liquefaction conditions.
