Kanab, UT: what USGS's seismic model says

Kanab 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. That puts Kanab in the 75th percentile nationally for seismic hazard - higher than 75% of the 4,875 US cities USGS was checked against here.

Where Kanab sits in Utah

USGS's underlying values for Kanab: 0.164g peak ground acceleration, 0.37g at short period, 0.126g at 1 second. Within Utah alone, Kanab ranks 93 of 95 cities by seismic hazard - the 2th percentile in-state. Kanab has a population of about 5,291.

Retrofit economics for Kanab

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 Utah 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 Utah.

Earthquake insurance for a Kanab home

A Kanab 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 Kanab's figures come from

Kanab'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 Kanab.
