Page, AZ: what USGS's seismic model says
Page carries Seismic Design Category C under USGS's ASCE 7-16 model. Moderate seismic hazard. Code adds irregular-building restrictions and requires bracing of some nonstructural components (e.g. tall shelving, water heaters) in addition to structural detailing. Rank it against the rest of the country and Page sits at the 74th percentile for seismic hazard among 4,875 US cities.
Page by the numbers
USGS's underlying values for Page: 0.146g peak ground acceleration, 0.31g at short period, 0.098g at 1 second. Within Arizona alone, Page ranks 7 of 57 cities by seismic hazard - the 89th percentile in-state. Page has a population of about 7,230.
What a retrofit costs in Page
A full earthquake retrofit typically runs $5,000-$10,000 nationally (around $7,000 typical), driven mainly by house size and foundation type, not by Arizona specifically. California's Earthquake Brace + Bolt grant, which covers a large share of this cost, is a California-only program and does not apply in Arizona.
Insuring against this, not just retrofitting
A Page homeowner cannot buy a standalone earthquake policy in most cases - it is added to an existing homeowners policy as an endorsement, so the place to start is a regular home-insurance quote.
Where Page's figures come from
Page's Category C and every number above trace to USGS's own ASCE 7-16 Design Maps service - see the methodology guide. See the category explainer for what Category C does and doesn't tell you about Page.
