Analyzing Terrorism Using Spatial Analysis Techniques: A Case Study of Turkish Cities

  • Chapter
  • First Online:
Evidence-Based Counterterrorism Policy

Abstract

This chapter examines techniques for studying terrorism attacks based on high risk locations within Turkey. According to the literature, spatial correlates that might aggravate terrorism risk include target vulnerability, population characteristics, crime, and physical infrastructure. Risk layers computed from these correlates were used along with actual terrorism incidents to calculate location quotients (LQs). LQs were mapped to identify cities in Turkey with the highest likelihood of attack. This analysis advocates the view that counterterrorism efforts can be based on a sound understanding of spatial attributes and structural qualities of a target area using standard geographic units. We discuss the importance of improving data for the development of more robust and accurate analysis.

Notes

  1. 1.

    For reference purposes, in other articles or studies, cities in Turkey have also been called provinces but the data was obtained from our Turkish sources who advised that these were deemed cities.

  2. 2.

    Domestic terrorism indicates terrorist activity by a group or groups within the country of attack.

  3. 3.

    This analysis was provided to the authors by the Turkish National Police, as were the data for city development, population, and numbers for assembly members, mosques, and murder convictions.

  4. 4.

    Hamm (2005) examined crimes ranging from motor vehicle violations, immigration fraud, and manufacturing illegal firearms to counterfeiting, armed bank robbery, smuggling weapons of mass destruction, and transnational organized crime.

  5. 5.

    Please keep in mind that these steps are for use of RTM without address level or XY coordinate data; if you have that coordinate information, use the steps in Caplan & Kennedy RTM Manual from (http://www.riskterrainmodeling.com).

  6. 6.

    “No risk” was not a categorization as no city lacked data that could plausibly aggravate terrorism risk according to the available empirical literature.

  7. 7.

    Osmaniye, Duzce, Kilis, Karabuk, and Yalova did not have a risk value calculated (data were missing for each of these cities in one or more risk terrain).
