The Philippines is a country prone to natural disasters. Located along the typhoon belt in the Pacific, the country is visited by an average of 20 typhoons every year. It is also situated in the Pacific Ring of Fire, making it vulnerable to frequent earthquakes and volcanic eruptions [src]. In recent years, typhoons have hit the country, causing deaths, flooding, and damaged properties.

One primary cause of deaths during these disasters is poorly built buildings that collapse, forming hazards rather than shelters. Most of the damaged buildings are built with traditional methods and materials, usually without regard to ensuring the structures withstand strong winds or major earthquakes.

While a house made of wood generally fares better than a concrete house in an earthquake, the opposite is true for a typhoon. This makes building earthquake and typhoon-proof homes in the Philippines a bit tricky.

How do you build safer homes?

Here’s a list of recommendations from a paper written by Louise Mattsson.

  • Avoid building in a disaster-prone area, if possible
  • Build on hard soil
  • Build on flat land
  • Provide for good drainage in the site
  • Plant trees to protect from wind
  • Choose a square or rectangular shape, or divide asymmetric shapes into several separated rectangles
  • Have small and few opening
  • Place openings on the opposite sides of the building
  • Have the same size and placement of opening on all floors
  • Anchor wooden house in a heavy and deep foundation
  • Connect all wooden members with straps, brackets, and gusset plats
  • Use diagonal trusses or plywood to brace the wooden framework
  • Reinforce masonry both vertically and horizontally around openings and in corners
  • Tie all masonry walls together with a continuous steel band or concrete beams placed in the top of the walls
  • Make sure that all connections are strong, especially the connection between walls and roof
  • Shape the roof pyramidal with a pitch of 30-40 degrees
  • Use light materials for the roof, such as wood and corrugated iron
  • Anchor the roof overhang to the walls.
