What materials can you use to make your house earthquake resistant?
Brick and concrete buildings have low ductility and therefore absorb very little energy. This makes them especially vulnerable in even minor earthquakes. Buildings constructed of steel-reinforced concrete, on the other hand, perform much better because the embedded steel increases the ductility of the material.

That must have been a terrifying experience for you. Can you explain some of the most important elements that go into building homes that can survive and protect from the impacts of earthquakes?
Bill: Earthquakes by nature are either a sideways shaking or an up-and-down shaking (or a combination of both). They’re unpredictable, and at their worst, can cause widespread damage and destruction. Houses built now aren’t necessarily designed to withstand earthquakes without damage but are designed to save lives.
What are some factors that allow homes or other buildings to fail in an earthquake?
Bill: There are several factors that happen in an earthquake that all affect buildings. On sloping ground and hillsides, there is a risk of slips and rockfalls. On flat ground, a high water table can cause liquefaction where water is forced to the surface, provoking surface flooding.
What are the most common materials used when building homes to withstand earthquakes?
Bill: As mentioned earlier, the main focus with building houses in earthquake zones is saving lives, and it’s secondary to build a house that is earthquake resistant. Cost is also a factor because an earthquake resistant house costs more.
What is the cost of the required earthquake and climate protections?
Bill: Building houses here is more along the lines of creating a safe environment rather than structural benefits. Most customers are not aware that the house they live in is designed to also save them if the big shake happens.
Has it been harder to get the materials you need due to the shortages and increased pricing caused by the pandemic?
