| Zusammenfassung |
| Seismic risk mitigation comprises of land-use planning policies that enable
risk reduction in areas exposed to earthquakes. Thus, the assessment of
land-use plans regarding urban growth in seismic prone areas is very
important. This article analyses the urban expansion of Vila Franca do Campo
(island of S. Miguel, Azores, Portugal) from 1994 to 2005 based on
ortophotomaps interpretations and simulates a scenario of urban growth for
the year 2016 with a Land-use and Cover-Change (LUCC) model (Geomod). The goal
is to evaluate the potential impact of land-use plans in managing urban
growth and promoting seismic risk mitigation. Results indicate that the
urban expansion, between 1994 and 2005, was done according to the Municipal
Master Plan (MMP) restrictions. The scenario modelled for the year 2016 is
potentially stricter for urban growth because it adds to the previous plan
the constraints defined by the South Coast Management Plan (SCMP) that
entered into force in 2007. In both time periods, a continuing urban growth
towards seismic areas was identified. The absence of seismic risk mitigation
policies and measures on both plans may contribute to increase the seismic
hazard exposure and vulnerability. The results of this study strongly
suggest the reformulation of future land-use plans to include seismic risk
mitigation goals and policies. |
