Open Source Mapping for Earthquake Risk Assessment and Reduction
This study explores the use of open-source mapping tools for earthquake risk assessment and reduction, emphasizing the importance of utilizing Free and Open Source Software (FOSS) in disaster management. By leveraging freely available geospatial data and software, individuals can identify vulnerable areas and infrastructure, particularly in developing countries with limited geospatial infrastructure.

Open Source Mapping for Earthquake Risk Assessment and Risk Reduction Richard Hinton, MGIS Candidate Dr. Anthony Robinson, Adviser
Outline Introduction Emergency Response Cycle Current Geospatial Frameworks Purposed Methodology Data Considerations Open Source in Disaster Management The Road Ahead Closing thoughts
Current Geospatial Frameworks/Initiatives Developed countries often have preparedness plans available www.ready.gov www.ncdp.mailman.columbia.edu
Current Geospatial Frameworks/Initiatives www.dpri.kyoto-u.ac.jp www.gazi.edu.tr www.fema.gov/hazus
Motivation Developing countries often lack the geospatial infrastructure Use GIS to facilitate disaster reduction through vulnerability assessment Use only Free and Open Source Software (FOSS) and data Can help minimize procurement resources Provides agility and flexibility (no vendor lock-in) End result: most anyone, with some training, can identify areas and infrastructure vulnerable to earthquakes, using only freely available data and software
Proposed Methodology 5 stages: 1. Site location 2. Search for and procure data 3. Identify gaps and resolve if possible 4. Edit data to ensure compatibility 5. Perform analysis
Proposed Methodology cont Not used to predict casualty figures To predict casualty figures HAZUS-MH- Hazard U.S. Multi Hazard www.fema.gov/hazus CATS - Consequences Assessment Tool Set www.saic.com/products/security/cats/
Proposed Methodology cont PAGER Prompt Assessment of Global Earthquakes for Response http://earthquake.usgs.gov/research/pager/ InaSAFE - IndonesiaScenario Assessment for Emergences inasafe.readthedocs.org
Data Considerations Data Sources: Open Source Free Including Crowd-sourced Primary Data Concerns: Quality Usability Security Crowd-sourced proven useable: Geocoding data project - proved to be 85% accurate www.usaid.gov Ushahidi-Haiti Project www.ushahidi.com
Data Considerations Common datasets include: Administrative boundaries and populated places Hydrography Topography Land cover and land use Utilities Critical infrastructure Demographic data Disaster specific datasets for earthquakes: Fault lines Historical seismic activity Soil classification
Data Considerations Issues with data from various sources: Access Interoperability Scale Accuracy Currency Coordinate system Redundancy Issues with data from developing countries Slow/intermittent Internet connection

Closing Thoughts Open Source has been used with success Community involvement With little training, areas and infrastructure at risk can be identified Every community has it s own specific needs Communities change over time
