Smart Visualization of Urban Area Earthquake Simulation

抄録

 Smart visualization of output from Integrated Earthquake Simulation (IES) performed for various earthquake scenarios is studied by taking advantage of existing methodology of big data visualization and by developing our own methodology which is suitable for earthquake disaster assessment. A key issue of being smart is to deliver information generated by IES to not only professional earthquake engineers, but also non-professional government officials and city residents. Simple visualization for city residents, wide area visualization for government officials, and dual visualization for professional engineers are proposed to bring common recognition to IES users. As a trial of smart visualization, both structure-wise and scenariowise damage condition statistics are graphed by means of histograms and mosaic plots; spatial clustering analysis for damaged structures is introduced and the distance between the damage conditions of earthquake scenarios is defined and visualized, accompanied by scenario cluster analysis.
