In July of this year, North America’s west coast experienced a string of earthquakes, some rating as high as 6.7 in magnitude. This recent seismic activity has left many people worried and wondering if these quakes are just par-for-the-course or a sign of something worse to come. Speaking to the Vancouver Sun, Simon Fraser University geologist Ben Ward says that people should be slightly ...
Elements at risk include buildings, transportation networks, lifelines, essential facilities, population data, agriculture data, economic data and ecological data (elements at risk in this project are limited to a narrow town area). Triggering factors include rainfall, temperature data, evapotranspiration, ground ...
Abstract The visualization of earthquake data in conjunction with surface imagery is an ideal application for three dimensional computer software. Downloading earthquake epicenter data, satellite imagery, and surface topography from the Internet is a relatively simple process. ...
In this context, the present paper collects the seismic analysis of a school building in reinforced concrete, illustrating the different stages concerning the acquisition of geometrical and mechanical data, problems about structural modelling and the features of the seismic retrofitting proposed. In closing, a critical comparison between the results derived from some techniques ...
The overwhelming humanitarian impact of the January 2010 Earthquake in Haiti created a tremendous coordination challenge for the humanitarian relief agencies. In this paper, we first describe the coordination mechanisms that are implemented by the United Nations and the role of its Office for the Coordination of Humanitarian Affairs (OCHA). We introduce the cluster approach, which is instrumental ...
Researchers writing in Disasters evaluated the experiences of Harvard University's Center for Geographic Analysis (CGA) during the Sichuan and Haiti earthquake responses in 2008 and 2010, respectively. They found that the conventional 'top-down' method of establishing emergency centres in damaged areas — usually managed by governments or relief agencies, to provide ...
The destructive effects of disasters on vulnerable populations will continue to increase as global inhabitants grow in numbers and occupy marginal, often hazard-prone areas. Recent experience has shown that there is a gap between available Geographic Information System technologies and geo-information management tools and their employment during disaster response operations. The goal of this ...
Travel behaviours were examined following the earthquake of 6.8 magnitude in Gisborne, New Zealand, on 20 December 2007. Surveys were returned from 438 households detailing their travel and information-seeking immediately after the earthquake. Although 85% of people experienced the earthquake at home, a volume of traffic that approximated peak weekday conditions was generated within an hour of ...
Damage estimation relationships have been proposed based on seismic ground motions and pipeline damage records from past earthquakes as a technique for understanding damage in future seismic hazards. ...
A computer-aided personal interviewing survey containing 63 items examining post-earthquake travel behaviours was administered to 802 members of the general public. Earthquake simulation videos modelled a moderate and severe event (6.8 and 7.5, respectively, on the Richter scale) in an office and home setting. Travel movements were recorded over a simulated 48-h period following the earthquake. ...
Surveyed areas were the damaged areas of Tottori-Seibu Earthquake (2000) and Miyagi-Hokubu Earthquake (2003) in Japan. Using survey data, discrete choice models on households' actual and hypothetical choices were constructed. ...
The proposed method is based on generating a geographical database with different variables that are related to human activity, considering factors of potential reduction and increase of damage caused by a future earthquake. The spatial information was obtained from different sources, mainly remote sensing images, national and local census and field data ...
This paper describes the organisation and operation of the Earthquake Investigation Committee of the Technical Council on Lifeline Earthquake Engineering. ...
The basic module of such a conceptualised DSS is the GIS (Geographical Information System) of the area covered by the project with all necessary data about the region. Using a combination of GIS and multicriteria methods, according to dominant natural catastrophes such as earthquakes, floods, weather, wildfires and others, data about the ...
The prediction of pore-water pressure buildup in sands caused by undrained cyclic loading is one of the key items in evaluating the potential for liquefaction of sandy sites during earthquakes. Presented herein are data indicating that, in strain-controlled tests, there is a predictable correlation between cyclic shear strain, number of cycles, and pore-water ...
