Q: What can I expect during the earthquake retrofitting process?

• <div><p>First, you can expect the project to be loud. If you have pets, you might want to take them to a friend's house during the day so they are not disturbed by any of the loud noises. In addition, you&rsquo;ll need to provide the retrofit team access to areas of the house that will need to be worked on, meaning you&rsquo;ll need to relocate personal items, clear clutter, and make pathways for the crew. Once the project is complete, a local building inspector will conduct a final inspection to ensure that the retrofitting is up to code.</p></div>

Q: What Is a gas shut-off valve for earthquakes?

• <div><p>Earthquake gas shut-off valves, or seismic gas shut-off valves, are safety devices that attach to your natural gas line. When an earthquake hits, the valve automatically turns off the flow of gas. Earthquake gas shut-off valves can prevent gas leaks, which are especially dangerous after a quake due to the risk of fire and explosion.</p></div>

Q: Are brick houses safer in an earthquake?

• <div><p>According to the <a href="https://www.earthquakecountry.org/step4/urmwalls/#:~:text=Houses%20built%20of%20unreinforced%20masonry,and%20the%20roof%20is%20critical.">Earthquake Country Alliance</a>&mdash;a public and private alliance in California that works to improve earthquake and tsunami readiness&mdash;reports that unreinforced masonry, such as stone, bricks, and hollow clay tiles, is more susceptible to earthquake damage.
