Earthquake Spatial Mitigation: Wenchuan, China and Los Baños, Philippines Case Studies

  • Jon Bryan Burley

Abstract

Planners, designers, government officials and citizens
are interested in creating safe environments, such as in mitigating
the effects of earthquakes. In this investigation, various landscapes
associated with the Wenchuan earthquake in China are examined
to assess environmental safety. Three landscape treatments (k=3)
were assessed by seven variables (b=7). The study employed the
Freidman analysis of variance statistics to test the treatments,
resulting in the confirmation that some treatments were
significantly better and safer than other designs (p≤0.05). The
designs that were significantly more safe include spaces where the
buildings are less tall, there is more space between the building,
the buildings are neither in the floodplain nor in landslide zones,
there are many escape routes for people experiencing and
earthquake and there are large open environments for refugees
and the transportation provided by helicopters. If such principles
were in common practice during the 20th century, approximately
421,000 earthquake-related deaths could have been avoided. The
assessment variables were then applied to a portion of Laguna
Province, Philippines, near Los Baños an area known for
substantial earthquakes. This area was assessed to be more safe
in a post-earthquake event, as the landscape is much less confining,
facilitating safety, rescue, and relief operations.
