Damage Estimation of the Next Tokyo Metropolitan Earthquake and Mitigation Measures

Real-time Seismology and Earthquake Damage Mitigation

■ Abstract Real-time seismology refers to a practice in which seismic data are collected and analyzed quickly after a significant seismic event, so that the results can be effectively used for postearthquake emergency response and early warning. As the technology of seismic instrumentation, telemetry, computers, and data storage facility advances, the real-time seismology for rapid postearthqua...

Estimation of Earthquake Damage Through Radar Interferometry (Case study: Bam 2003 Earthquake)

The estimate of the damage caused by the earthquake and other natural disasters in the first days after the occurrence of these events can provide a quick damages assessment and help to manage the crisis. Several methods are available to investigate the extent of earthquake’s damage. Optical remote sensing, photogrammetric methods (UAVs and LIDARs), radar interferometry (InSAR) and field observ...

Earthquake Loss Estimation Including Transportation Network Damage

Large earthquakes have the potential of causing extensive damage and enormous economic losses. These losses are primarily attributable to the reduction in functionality of various facilities in the affected region and the rebuilding costs, and can be reduced through strategic preand post-earthquake decisions. This thesis describes an integrated methodology to estimate losses due to scenario ear...

Estimation of Turbulent Diffusivity over the Tokyo Metropolitan Area from Constant-volume Balloons

In order to study the characteristics of turbulent diffusion over an urban area, constant-volume balloons with transponders were released at altitudes of 200 and 400 m, and their behavior was observed over the Tokyo Metropolitan area. The atmospheric diffusivities are derived from the Lagrangian properties of the balloons, in relation to the temperature lapse rate and the turbulent intensity. T...
