Appropriately constructed or strengthened buildings are less likely to collapse or sustain significant damage. Therefore, they reduce the potential of damaging the buildings' gas systems. Consider taking steps to ensure that your buildings are structurally designed and constructed or retrofitted to withstand a significant earthquake.
