Clanton's Seismic Design Category, explained

USGS's ASCE 7-16 seismic design model - the same standard building codes use - places Clanton in Seismic Design Category C: 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. Nationally, Clanton ranks above 71% of the 4,875 cities in this dataset for seismic hazard - the 71th percentile.

How Clanton compares

USGS's underlying values for Clanton: 0.116g peak ground acceleration, 0.213g at short period, 0.085g at 1 second. Within Alabama alone, Clanton ranks 64 of 107 cities by seismic hazard - the 41th percentile in-state. Clanton has a population of about 9,228.

Retrofit economics for Clanton

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 Alabama 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 Alabama.

Earthquake insurance for a Clanton home

A Clanton 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 Clanton's figures come from

Clanton'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 Clanton.
